What is Summerween

So, what is Summerween exactly? It’s a playful celebration that mixes Halloween themes with summertime energy. Instead of waiting until October, people celebrate early—with creepy costumes, themed treats, haunted pool parties, and candy galore.

The idea comes from the animated show Gravity Falls, where residents love Halloween so much, they celebrate it twice a year. They even have their own villain—the Summerween Trickster. Thanks to that show, fans started bringing the concept to real life.

When is Summerween

You’re probably wondering—when is Summerween celebrated?

While there’s no strict calendar date, most parties and events happen in late June. In 2025, Summerween will fall on June 28, the second-to-last Friday of the month. That’s become the unofficial day for most Summerween celebrations.

Some towns and communities stretch it out a bit. For instance, Summerween in Salem, Massachusetts will take place July 19–21, 2025. That weekend, Blackcraft Salem is planning movie nights, a themed café menu, giveaways, and live haunted actors. A sample sale and spooky gifts with purchase? Count us in.

In short—any time from June through August is fair game. Just pick a weekend, plan your costume, and start decorating.

Decor is where the magic happens. And here’s where All Cotton and Linen can help.

Summerween Trickster

No Summerween talk is complete without the Summerween Trickster. He’s the candy-obsessed villain from Gravity Falls who shows up if you don’t give out enough candy.

While he’s fictional, the Trickster adds fun to the theme. Some parties even include Trickster-themed games. Hide candy around your yard and have guests search for it—or create a mini escape room challenge where the Trickster has to be defeated by solving clues.

You can even turn it into a costume contest: Who can be the creepiest Summerween Trickster? Extra points for creativity and candy bribes.

So, what is Summerween? It’s a summer spin on spooky fun. It lets you enjoy everything you love about Halloween—without the sweaters or chilly nights.
