The Official Project Glow Fest After Party with DJ Mandy lands at Transmission in Washington, DC on Saturday, May 30, and the outdoor venue means the weather is as much a part of your night as the music. With a mostly sunny day topping out near 75°F and a northwest wind running 6 to 9 mph, expect a genuinely beautiful spring evening — cool enough to dance without overheating, breezy enough that you’ll want to think about what you’re wearing.
What the Weather Looks Like
The National Weather Service calls for mostly sunny skies Saturday with a high near 75°F. Rain chances sit at just 13%, so the forecast is firmly in your favor. By the time the event kicks off at 10 PM ET, temperatures will have dropped from that afternoon peak — a northwest breeze at 6 to 9 mph will make it feel crisp. This is a spring night in DC, not a summer one.
Dress the Part (and the Temperature)
Layer up smart. Start with a festival-light look — tank top, mesh, whatever fits the rave aesthetic — and bring something to tie around your waist when the wind picks up later. Skip the flip-flops; comfortable walking sandals are your best bet for navigating an outdoor venue through a late-night set without destroying your feet.
This is the Official Project Glow After Party, which means one thing: go all in on the look. Slather on body glitter gel before you leave the house. This is exactly the crowd and the night it’s made for.
Pack Your Glow Bag
Most outdoor venues require a clear stadium bag — get yours sorted before the night so you’re not scrambling at the gate. Here’s what goes inside:
- Portable phone charger 20000mah — a long outdoor set with no wall outlets will kill your battery before the headliner drops. Non-negotiable.
- Hydration backpack — staying hydrated at a rave is easier when you’re not fighting the bar line every 45 minutes. Throw it on and focus on the music.
- Bandana face cover — with a steady northwest breeze, this doubles as both a windbreak and a look. Wind at outdoor venues picks up in open areas; your face will thank you.
Beat the Late-Night Chill
Spring evenings in DC cool faster than people expect, especially once the sun is long gone and a northwest wind is still kicking. A portable blanket waterproof packs flat into your bag, works as a ground cover, and becomes a lifesaver around 1 AM when the temperature dips and you still want to stay for the last track.
Practical Tips
- The event starts at 10 PM ET — arrive early to clear security and settle in before the set begins.
- Outdoor venues mean uneven ground; wear shoes you can move in for hours.
- Rain odds are low at 13%, but a light layer in your bag hedges against any brief shower.
- Check Transmission’s official channels for their bag policy and prohibited items before you head out — policies vary and the clear bag requirement is common but worth confirming.
The forecast is about as good as a late-May outdoor show in DC gets. Now figure out your glitter situation and enjoy the night.
