We get it, it’s hot. But before we know it, we’ll be moping about early sunsets and snow, so take advantage of all these outdoor festivals, fitness classes, and movie screenings while you can.

Go ahead, see Black Panther again
Catch Black Panther for the 135,895th time this year, but this time for free. Geek Nite Out—the Meetup group for well, geek stuff—is hosting an outdoor screening. Bring along a picnic and a blanket and try not to quote every line, even though we all probably could by now.
Farragut Square, Friday, 7:30 p.m.-11:30 p.m., register here.

Work out in luxury
Rosewood, the luxury hotel in Georgetown, and Lululemon, the luxury fitness brand, are teaming up to shower us freeloaders in the finer things. Head to the hotel’s rooftop on Saturday, which will be transformed into an open-air studio for a free hour-long vinyasa-style yoga class. The classes will recur each weekend this month. And if you find a way to sneak some tiny shampoos into your gym bag, we won’t tell.
Rosewood Washington D.C., Saturday, 8 a.m.-9 a.m., register by calling 202-617-2400 or emailing washingtondc.butlers@rosewoodhotels.com.

Party, but feel good about it
An outdoor festival is great. An outdoor festival in the name of civic engagement is even better. Local non-profits Washington Parks and People and The DC Tutoring and Mentoring Initiative are hosting CivicFest at Malcolm X Park on Saturday, where you can learn about their volunteer opportunities, catch some music, and grab food truck eats. If you just want to chill, practitioners of reiki, yoga, tai chi, and meditation will be leading workshops all day long.
Malcolm X Park, Saturday, noon-8 p.m., register here.

Ready your jazz hands
Every year, Signature Theatre throws open its doors for an open house, luring patrons in with the promise of deeply discounted tickets to plays and musicals. There’s plenty to do and see while you wait in line at the box office: Dancers, singers, and musicians will be putting on performances every 15 minutes throughout the day; there are dance classes and crafts inside; and free food and sno cones are available on the plaza outside. Plus they’ll be selling show merchandise—if your coffee mug collection has been lacking, you’re in luck here.
Signature Theatre, Sunday, noon-8:30 p.m.

See some art that’s tough
For its summer exhibit Heavy Metal, the National Museum of Women in the Arts celebrates female artists who’ve made metal their medium of choice (not that kind of metal). Check out jewelry, sculptures, and more from these artists, along with the museum’s permanent exhibits, at its monthly community day on Sunday. Head over at 1 p.m. for the Fierce Women tour, which celebrates female artists in the museum who persisted in their creative pursuits, despite being labeled as “unfeminine.” Should you feel any lingering guilt over not supporting the museum with an admission fee, spend that $10 at the extremely underrated gift shop, chock-full of books, toys, jewelry, candles, and more.
