1. Perfect beach weather
If us San Franciscans want to hang out in our bathing suits during the regular summer, we can head to any of Northern California’s amazing rivers or lakes. Then, when summer ends, the weather finally heats up just enough that we finally get even MORE beach days right in our very own 7x7. In case math is hard for you, that means we get five months of beach time compared to everyone else’s three.
2. Clear skies
Okay, so considering we’re in a drought, it might be a little gauche to brag about how it doesn’t rain in SF in September and October, but our point is that summer everywhere else seems to be full of unexpected thunderstorms that send you scrambling to grab your pool floats and towels before taking cover inside. That’s a thing that never, ever happens in SF. (Even when we want it to... sigh.)
3. No humidity
Thanks to the fact that SF is surrounded by water on three sides, it’s technically always humid here. But our humidity is nothing like that “WTF I can’t breathe and I’ve literally been outside for 30 seconds and I’m sweating in some really weird places right now” humidity they have during summer on the East Coast and in the South. That’s right: SF Indian summer is never "sweating in some really weird places right now" hot. And if that’s not winning, we don’t want to know what is.
