Just because Halloween’s in October doesn’t mean we have to wait for pumpkins and costumes.

The rise of summerween party events proves people love a good mashup, bringing spooky fun into the summer months.

It’s a new trend popping up everywhere, with folks hosting parties full of eerie treats, glow-in-the-dark games, water fights, and poolside costumes.

I’m all about summer—really, it’s my favorite season.

But, being able to toss in some playful Halloween chills just makes everything that much more festive.

If you also think a summer/October mix is some fun that could make your season, it’s time to get your friends and family together for Summerween.

So, grab a snack, settle in, and let’s get to planning this trending idea of the best summerween party this year!

Bringing Halloween to Summer: The Origins and Spirit of Summerween

It might feel a little odd at first—carving melons instead of pumpkins and trading falling leaves for backyard sprinklers.

But that simple swap is at the heart of Summerween.

The idea didn’t come out of nowhere.

It’s rooted in nostalgia, a love for the spooky season, and a wish for Halloween-style fun that lasts past October.

Where Summerween Started

It all started as a fun, fictional celebration on the animated show Gravity Falls, where the quirky town residents dress up in costumes, carve jack-o’-melons, and go trick-or-treating—in the middle of summer.

The idea quickly caught on with fans who wanted a second dose of Halloween magic without having to wait for October.

Now, people everywhere are bringing the haunted vibes to their summer BBQs with eerie décor, candy-filled piñatas, and poolside pumpkins.

Because why should October have all the spooky fun?

How to Throw the Ultimate Summerween Party

If you want to turn your summer weekend into pure Halloween joy, a Summerween bash is the way to go.

There’s something special about mixing costumes and candy with water balloons and sunshine.

With a little planning, you can make your party the highlight of the season.

Let’s talk about how to set the mood from start to finish, so guests remember your Summerween party long after the last popsicle melts.

Creative Invitations for a Spooky Bash

Every great party starts with a standout invite.

Whether you love hands-on projects or need something you can whip up fast, there are plenty of ways to set the Summerween mood right from the start.

• Free Printables: Make it easy and print out your Summerween party invitations for free at the end of this post! Simply fill them out and you’re all set!
• Digital Templates: Free tools like Canva or Adobe Express let you pull together ghostly pool floaties, watermelons, and bright suns in minutes. You can add clever lines like “Join us for tricks, treats, and tropical heat!”
• Themed Messaging: Channel your inner Halloween poet with wording that hints at spooky—but sunny—fun:
  • “You’re Invited to the Spookiest Beach Bash of the Summer!”
  • “Swimsuits and Skulls: Come Celebrate Summerween!”
  • “Costumes, Candy, and Poolside Chills Await—RSVP if You Dare!”
• DIY Physical Invites: If you want to go old-school or hand off invites at camp or work, try:
  • Decorating orange index cards with black bats or sunglasses-wearing skeletons.
  • Attaching invitations to mini plastic cauldrons, popsicle sticks, or glow sticks.
  • Using watermelon-shaped paper and drawing jack-o’-lantern faces.

The key is to use summer colors with a twist of Halloween—think lime, purple, black, and neon orange.

Summerween Party Decorations

Decorating for Summerween is about striking the perfect balance.

Start with simple summer items—think beach balls, pool toys, or picnic tables—and give them a spooky twist.

Here are a few ideas to turn your space into a Summerween masterpiece:

• Carve Watermelons: Swap pumpkins for watermelons. Cut creepy or silly faces, pop in LED candles, and line walkways or the pool edge.
• Bright Banners and Streamers: Mix classic Halloween icons (witch hats, bats, spiders) with pineapple garlands, tropical flowers, or pastel paper fans.

• Outdoor Lights: Hang orange and purple string lights, lanterns, or even witch hat lights in the trees or along fences.
• Table Settings: Use paper plates with jack-o’-lantern faces, napkins in bold colors, and serve drinks in jars with striped straws or plastic eyeballs.
• DIY Touches:
  • Spray-paint skeletons neon green or purple.
  • Fill clear vases with gummy worms and colorful drink umbrellas.
  • Create a “witch’s beach bar” sign and stick near the party area.

A little creativity goes a long way. The more playful, the better—this holiday is all about fun, not perfection.

Curating the Perfect Summerween Party Playlist

Music makes the mood.

For Summerween, you need tunes that get people laughing, dancing, and maybe feeling a little spooky as the sun starts to set.

Here’s how to build the perfect playlist:

1. Start with Halloween Classics: Mix in songs like:
   • “Monster Mash” (Bobby “Boris” Pickett)
   • “Thriller” (Michael Jackson)
   • “Ghostbusters” (Ray Parker Jr.)
   • “Somebody’s Watching Me” (Rockwell)
2. Add Summer Hits:
   • “Walking on Sunshine” (Katrina and the Waves)
   • “Cake by the Ocean” (DNCE)
   • “Hot in Herre” (Nelly)
   • “Can’t Stop the Feeling!” (Justin Timberlake)
3. Mix in Mashups & Remixes: Look for DJ mixes or playlists online that blend Halloween with summer. There are tons of mashups and dance mixes that will keep guests moving.
4. Sprinkle in Silly Songs & Movie Themes: Nothing says party like recognizing a theme from “Hocus Pocus,” “Beetlejuice,” or the “Addams Family.”

Pro tip: Make the first half of your playlist upbeat for pool games or daylight. As the sky gets dark, turn up the spooky tunes and glow-in-the-dark effects. Use a Bluetooth speaker or two, and keep the volume just right for chatting and having a blast.

Summerween Party Food

Any real Summerween party needs food and drinks that show off both your spooky side and love for breezy summer snacks.

Themed treats, clever finger foods, and cool drinks are sure to get everyone talking (and coming back for seconds).

The secret is to work in bright colors, classic Halloween shapes, and summer flavors that keep everything fresh and fun.

Alcoholic Drink Ideas

Summerween is the perfect excuse for silly, boozy drinks with a splash of spooky.

Some favorites to wow your party guests:

• Ghoul-Aid Sangria: Mix white wine with tart cranberry juice, orange liqueur, and lots of sliced oranges, limes, and berries. Drop in gummy eyeballs for a gory twist.
• Witch’s Brew Margaritas: Blend tequila, blue curaçao, fresh lime, and pineapple juice. Rim glasses with purple or green colored sugar, then add a plastic spider or bat ring to each glass.
• Bloody Sunrise: Pour tequila, orange juice, and a slow drizzle of grenadine over ice. It sinks to the bottom, creating “bloody” layers.
• Black Lagoon Mojitos: Muddle blackberries with mint and rum, add a bit of lime, and top with sparkling water. Garnish with mint “seaweed” and a floating gummy fish.

Presentation tips:

• Use clear pitchers or punch bowls so everyone can see those wild colors and floating gummy candies.
• Freeze berries or grapes to use as spooky ice cubes that won’t water down drinks.
• Serve with striped straws, neon cocktail picks, or little plastic skulls for a hint of Halloween flair.

Non-alcoholic Drink Ideas

Kids and adults both love non-alcoholic sips.

You can make them just as festive as the grown-up drinks.

Try bright, cold concoctions like these:

• Monster Melon Punch: Puree watermelon and mix it with lemon-lime soda and a splash of lime juice. Float melon balls “eyeballs” and gummy worms across the top.
• Ghostly Lemonade: Lemonade with blue food coloring, floating marshmallow “ghosts,” and a rim of pink sugar. Add Swedish Fish or candy eyes for extra fun.
• Creepy Crawler Cooler: Pour grape juice, apple juice, and club soda over ice. Drop in plastic spiders on top or wrap the glass with spiderweb-patterned paper.
• Swamp Juice: Lime sherbet with lemon-lime soda and pineapple chunks. Stir until foamy and serve with a black licorice stick “swamp vine.”

Easy serving ideas:

• Use mason jars, or plastic cups with monster faces drawn on with permanent marker.
• Dress up drinks with paper umbrella “broomsticks” or candy blood bags (clear bags with cherry punch).
• Colorful straws and wild napkins always add to the fun.

Spooky Snacks

Summerween snacks should be easy to grab, playful, and just a bit mischievous.

Aim for a mix of salty, sweet, and a few slightly gross-out treats to keep everyone guessing.

Some top picks:

• Mummy Hot Dogs: Wrap mini sausages with strips of crescent roll dough. Bake until golden, then dot with mustard “eyes.”
• Monster Guac Cups: Fill clear shot glasses with guacamole. Top with two olive “eyeballs” on pretzel sticks. Serve with blue or orange tortilla chips.
• Witch Hat Nachos: Arrange round tortilla chips in a circle; top with a cone-shaped cheese crisp or bugle, and dot with salsa for a “buckle.”
• Cheesy Ghosts: Use a cookie cutter to slice ghost shapes from white cheddar. Add raisins or black olive bits for the eyes.

Main Course Food Menu Ideas

When it comes to serving food at your Summerween party, have fun with the presentation and let your spooky summer theme shine!

Here are a few delicious ideas to combine festive fright with summer fun:

• Vampire Sliders: Juicy mini burgers get a spooky upgrade with sharp cheddar “fangs” and a drizzle of “bloody” ketchup. Add a slice of red onion for a creepy grin and serve on toasted slider buns—perfect for little monsters and grown-up ghouls alike.

• Grilled “Monster” Tacos: Set up a taco bar with grilled meats, roasted veggies, and plenty of toppings like guacamole “slime,” olive “eyeballs,” and shredded lettuce “hair.” Guests can create their own monster tacos for a fun and festive twist.

• Jack-o’-Lantern Stuffed Peppers: Orange bell peppers carved like mini jack-o’-lanterns are stuffed with a flavorful mix of rice, seasoned beef or beans, and melted cheese. They’re spooky, satisfying, and super cute on a party platter.

• Witch’s Brew Mac & Cheese: This classic comfort food gets a magical makeover with food coloring to turn it green, purple, or even black! Top with sliced olives for “eyeballs” or swirl in different pasta shapes for a cauldron full of creepy fun.

• Swampy BBQ Chicken Sandwiches: Pulled BBQ chicken piled high on buns and drizzled with green ranch “slime” dressing. Add a crunchy slaw topping and serve with pickle “toads” on the side for a flavorful and freaky dish.

• Frankenstein Flatbreads: These mini flatbread pizzas are decorated to look like Frankenstein’s face using pesto “skin,” olive “bolts,” and pepperoni “eyes.” Let kids design their own creepy creations before baking them until bubbly.

• Zombie Rib Rack: Sticky BBQ ribs become “zombie bones” when arranged on a platter with a creepy sign. Serve with grilled corn and eerie side dishes for a hearty and haunted main course.

• Skeleton Chicken Drumsticks: Crispy grilled drumsticks stacked like skeletal limbs on a platter with a “skull” centerpiece made from a carved melon or bell pepper.

• Haunted Hawaiian Pizza Skewers: All the flavors of pizza on a stick—pineapple, mozzarella, pepperoni, and dough—grilled to perfection. Drizzle with ranch “ghost sauce” or spicy sriracha for a little Summerween heat.

• Spooky Spaghetti Nests: Twirl spaghetti into little nests and top with meatballs decorated as eyeballs using mozzarella slices and olives. A creepy-cute pasta dish that’s equal parts spooky and satisfying!

Serving Summerween main course menu items is all about mixing spooky fun with summertime flavors with a creepy twist!

Summerween Party Desserts

No Summerween party is complete without a spread of spooky-sweet desserts to satisfy your little ghosts and ghouls!

Here are a few spooky summer surprises:

• Jack-o’-Melon Fruit Salad: Carve a watermelon like a jack-o’-lantern and fill it with a mix of summer fruits like berries, grapes, and melon balls. It’s refreshing, spooky, and perfect for hot weather.
• Ghost S’mores Dip: Melt chocolate and marshmallows in a skillet, then top with ghost-shaped marshmallows and serve with graham crackers for dipping. It’s gooey, warm, and hauntingly good.
• Monster Eye Cake Pops: Cake pops coated in bright green or purple candy melts, decorated with candy eyeballs and sprinkles. These bite-sized treats are great for kids and easy to grab and go.
• Witch Hat Ice Cream Cones: Dip the edges of sugar cones in chocolate and sprinkles, then place them upside down on a scoop of ice cream to look like a witch’s hat. A magical way to cool down!
• Pumpkin Patch Dirt Cups: Layers of chocolate pudding, crushed Oreos, and gummy pumpkins or worms served in clear cups. Add a little green whipped topping “grass” for a spooky garden vibe.

Serving Summerween desserts is where the spooky magic really comes alive and is your chance to get creative with treats that are both eerie and irresistible.

Summerween Games and Activities

A great party is always about finding the right mix of games and activities to set the stage for a party no one forgets.

For Summerween, blending classic summer fun with Halloween-themed twists means there’s something for everyone.

Here are a few favorite ways to keep your party guests laughing, moving, and snapping those memory-making photos.

Summerween Party Games

Fun is at the heart of any great Summerween party.

Set up a few games that guests can dip in and out of, so no one feels left out or bored.

Here are some go-to ideas:

Witch Hat Ring Toss

Set up inflatable witch hats and use floating rings to toss over them. Players take turns trying to land rings on the hats for points.

Spider Hunt

Hide plastic spiders around the party area. Guests search for as many spiders as they can find within a set time. The person with the most spiders wins.

Summerween Party Treasure Hunt

Place small Halloween treasures around the party area. Give guests a map or clues to find the hidden treasures. The first to find all wins.

Floating Pumpkin Patch

If you’re hosting a pool party, set small floating pumpkins in the pool and have guests race to collect them. The person who gathers the most pumpkins wins.

Spooky Relay Race

A Halloween relay race with eyeballs on spoons is a hilarious way to get everyone moving and laughing. Add a spooky twist by having them weave through pumpkins or dodge “ghost” obstacles for extra fun.

Skeleton Hunt

Skeleton Scavenger Hunt is a bone-rattling blast for any Summerween party! Before the party, hide plastic skeleton parts (like arms, legs, skulls, and ribs) around your yard or party space. Split guests into teams and have them search for all the pieces to assemble a full skeleton—first team to complete their spooky skeleton wins a prize!

Candy Corn Bowling

Candy corn bowling is a festive summerween party game that adds a fun twist to traditional bowling. Instead of using standard bowling pins, participants set up candy corn-shaped pins arranged in a triangular formation. 

Halloween Bingo

Spooky Halloween bingo is a twist on the traditional bingo game and perfect for a backyard Summerween party game. Instead of regular bingo numbers, the game cards feature Halloween-themed images such as ghosts, witches, pumpkins, black cats, and more. 

Eyeball Pong

Eyeball pong is a Halloween-themed twist on the classic beer pong game, perfect for adding a spooky and fun element to your party. Instead of traditional ping pong balls, players use small plastic ping-pong balls with eyes, which add an eerie and festive touch to the game. 

Be sure to have some fun party game prizes that can be small bags of candy, bracelets, or a silly plastic trophy from the dollar store.

Create a Summerween Photo Booth

No Summerween party is complete without a photo booth!

Half the fun of enjoying a party is seeing how creative people get with the props and poses.

Here are some easy ways to build your own, even if you’re short on time or space:

Backdrops: Hang a black or purple tablecloth or blanket as your base. Add cut-out bats, fake cobwebs, or strands of orange lights. A string of tropical flowers or a few paper sunflowers keeps it summery.

Props: Mix up the usual Halloween stuff with beachy extras. Think witch hats and sunglasses, inflatable skeletons, pool float “lifebuoys,” or shark masks with leis. Toss in some silly signs, like “Here for the Boos” or “Ghouls Just Wanna Have Sun.”

Lighting: Outdoor patios are perfect for golden hour photos, but you can also use rows of battery-powered candles, string lights, or glow sticks in mason jars to set the mood after sunset.

Selfie Station: Set up a phone tripod to snap photos for guests. Keep a basket of props nearby so people can grab and go all night.

Printing Stations: Print a few instant snapshots on-site, so people have a keepsake from the party. If you like, make a quick digital album and share it out the next day.

Enjoy an Outdoor Scary Movie Night

When the sun dips and a breeze cools things off, nothing beats an outdoor movie for Summerween.

Here’s how to make it both cozy and just spooky enough for everyone:

• Setting Up: You can use a plain white sheet hung between trees or against a wall for your screen. Projectors are easy to rent or borrow these days; even a decent phone projector can do the trick for small groups.
• Seating: Toss down blankets, picnic mats, or old sleeping bags. Add a few bean bags, inflatable loungers, and heaps of pillows so everyone can sink in and get comfy.
• Atmosphere: Use strings of orange or purple lights, glow-in-the-dark decorations, or even some plastic tombstones. Give out blankets or beach towels for a warm but eerie touch.
• Movie Picks: It’s fun to keep movies a little spooky, but not nightmare fuel.
  
  Here are some fun choices:
  • “Hocus Pocus”
  • “Hotel Transylvania”
  • “Jaws” (a summer classic with a scare) or
  • “The Addams Family”
  • “Ghostbusters”

If you keep it relaxed and make the space feel special, folks will linger long after the credits roll.

Host a Summerween Costume Contest

Costumes are the highlight for most guests, even when the temperature climbs.

The trick is to balance creepy and cool (as in temperature!).

Here are a few favorite ideas and tips for a successful Summerween costume contest:

• Swimsuit Mashups: Encourage guests to pair bathing suits or trunks with spooky accessories. Think skeleton rash guards, vampire capes with neon goggles, or a witch hat with a sarong.
• Classic with a Twist: Pirate, mermaid, or lifeguard costumes are easy fits for summer. Add fangs, green face paint, or safety-pinned spiders for the “ween” vibe.
• Group Themes: Suggest groups dress as “Undead Lifeguards,” “Haunted Surfers,” or “Zombie Synchronized Swimmers.” Siblings and friends love to team up.
• Easy DIYs: Swim cover-ups become ghosts. Beach towels double as superhero capes. Sunglasses, flip-flops, and hats can all be given a silly or scary upgrade.
• Age-Friendly: Make sure to invite adults and kids to join in. Even a funny T-shirt with a spooky saying counts.

At the end of the night, have everyone vote for their favorites and give out prizes for categories like “Funniest,” “Scariest,” and “Most Creative.”

Summerween Party Favors

Party favors are the cherry on top of any celebration, and Summerween is no exception.

I love giving guests a little something special to help them remember the event.

It doesn’t have to be expensive or over-the-top.

Small treats, quirky surprises, or handmade crafts always bring out big smiles.

Let’s make sure your guests leave with something that feels both summery and a little spooky.

Here are a few ideas to gift guests:

Glow-in-the-Dark Slime Jars

Send guests home with mini jars of homemade or store-bought glow slime in neon green or purple. Add a “Witch’s Ooze” or “Monster Muck” label for a fun, spooky twist.

Spooky Sunglasses

Pair Halloween with fun by giving out glow in the dark glasses. They’re playful, cool, and perfect for outdoor Summerween night party fun.

Mini Cauldron Candy Cups

Fill tiny cauldrons with Halloween candy, gummy worms, or colorful jelly beans. Wrap them in cellophane and tie them with ribbon for a treat bag that feels both festive and frightful.

Drink Pouches

Create custom drink pouches filled with tropical juice or flavored water, decorated with jack-o’-lantern or bat stickers.

Halloween Bracelets

Hand out some Halloween bracelets as wearable summerween party favors. These are perfect so enjoy in the summer and still great for the upcoming Halloween season in October!

Mix and match a few of these ideas and you’ll send everyone home smiling, still talking about your Summerween party for days to come.

Final Thoughts

Mixing the sunshine of summer with the fun of Halloween is my favorite recipe for a party everyone will remember.

There’s something about silly costumes, bright drinks, and a splash of spooky that turns an ordinary summer day into pure joy.

Summerween isn’t just a themed party—it’s the start of a new tradition where anything goes and everyone feels welcome.
