Pumpkins on the porch. Ghosts in the backyard. A costume party in July. Summerween has turned into one of the season's most talked-about trends, as the holiday has become an occasion that is far too fun to wait until October to celebrate.
Homeowners, party planners, and Halloween lovers are moving up the calendar and celebrating the spooky season early, mixing pool floats with jack-o-lanterns and sunscreen with skeletons. This guide covers what Summerween is, where the idea came from, when to celebrate it, and how to decorate and throw a party that pulls off both seasons at once.
What is Summerween?
Summerween is exactly what it sounds like: Halloween, celebrated in summer. This means pumpkins by the pool, skeletons in beach chairs, and costume parties held under a July sun instead of an October chill. It's a chance to enjoy Halloween's best parts — the decor, the costumes, the candy, the theme — without waiting for fall.
The best part about Summerween is that there are no rules. There's no official date on the calendar, no required decorations, and no limit to how far you take it. You can go full spooky with skeletons and cobwebs, keep it light with pumpkins and string lights, or blend Halloween icons with beach and pool themes. However you want to combine the two seasons is completely up to you.
Where Did Summerween Come From?
Summerween traces back to the animated series Gravity Falls, which introduced the holiday in a 2012 episode centered on a town celebrating Halloween in the summer because they couldn't wait for the real thing. The idea caught on with fans, and what started as a fictional holiday turned into a real one, celebrated by Halloween fans, party hosts, and retailers who wanted an excuse to bring out the decorations early.
When Does Summerween Start?
There's no fixed start date for Summerween, and that's part of the appeal. Some people celebrate in early June, others wait until late August, and plenty just pick a random summer weekend that works for their schedule. The only real rule is to pick a date and commit to it. Once you've chosen your Summerween date, treat it like any other holiday: plan the party, put up the decorations, and enjoy it.
How to Celebrate Summerween Ideas
Summerween Activities & Party Ideas
A Summerween party works best when it borrows from both seasons. Here are a few ideas to build the celebration around:
-
Costume party: Ask guests to dress up in Halloween costumes, summer-themed costumes, or a mashup of both.
-
Spooky outdoor movie night: Set up a projector in the backyard and screen a Halloween classic under the stars.
-
Halloween-themed BBQ: Grill up dinner and serve it alongside candy corn, mummy-inspired hot dogs, or a pumpkin-shaped cake.
-
Backyard scavenger hunt: Hide candy or glow-in-the-dark skeletons or plastic pumpkins around the yard for kids to find after dark.
-
Campfire ghost stories: Pull out the s'mores kit and swap stories once the sun goes down.
Summerween Decorating Ideas
Indoor Decorating
Bring the Summerween theme inside with a mix of lighting and small decor pieces. Our Halloween Lights collection includes infinity lights, light-up pumpkins, and glowing figurines that work well on a mantel, shelf, or entryway table. Pair them with Halloween Figurines or a Halloween Snowglobe for a tabletop display, and round out the look with a few pumpkins placed around the house.
Outdoor and Front Door Decorating
Your front porch is where Summerween decor gets to have the most fun. Start with a few huge artificial pumpkins flanking the door or lining the walkway for an instant seasonal statement.
Our large Halloween decorations also make great candidates for a Summerween makeover: a lei around a skeleton's neck, sunglasses on a witch, or tropical flowers tucked into a scarecrow display all turn a standard Halloween statue into something that fits the summer setting.
Infinity lights add great evening ambience, but they're built for covered outdoor use only since they aren't waterproof. Place them under a covered porch or pergola, or along a window frame from inside facing out.
For the front door, take a Halloween wreath as your base and decorate it with summer picks and sprays — tropical leaves, sunflowers, and bright berries all work well against a Halloween backdrop. Our Christmas Tree Picks & Sprays collection has plenty of options to mix in.
For garland, the Autumnal Gourd/Berry Garland drapes easily along a railing or doorframe, bringing seasonal gourds and berries into the mix.
Halloween topiaries fit the Summerween mood well. Surround them with a mix of pumpkins in different sizes and colors, add a few potted mums, and the display comes together without much effort.
A Halloween tree works exactly like a Christmas tree, just swapped for the season. Start with a small evergreen in a basket or planter and hang it with Halloween-themed ornaments — pumpkin pie slices are a popular choice!
DIY Ideas
If you'd rather make than buy, a few DIY projects fit the Summerween theme well:
-
Painted summer pumpkins: Skip the carving and paint pumpkins in bright summer colors or tropical patterns instead.
-
Pumpkin flower pot: Hollow out a pumpkin and use it as a planter for summer flowers.
-
Pineapple or watermelon jack-o-lantern: Carve a face into a pineapple or watermelon for a summer spin on the classic jack-o-lantern.
-
Ghost luminary jars: Wrap a mason jar in white tissue paper, add a face with a marker, and drop in a battery-operated candle.
Summerween is proof that Halloween doesn't have to wait for October. Pick a date, pull out the decorations, and let the two seasons meet in the middle.
