“The coldest winter I ever spent was a summer in San Francisco.”
OK, so Mark Twain may never have actually said it himself. But the statement stands regardless.
As any naive tourist shivering miserably in a tank top and Bermuda shorts might attest, San Francisco in the summertime can be one chilly town, especially in early summer.
Welcome to the infamous “June Gloom.”
Even on days when the temperature in nearby cities climbs into the glorious 90s (F), it’s not uncommon to find much of San Francisco shrouded in a thick blanket of bone-chilling fog.
If you’re still a bit foggy (sorry, couldn’t resist) about why that is, scroll through this interactive explainer created by Newsbound.
For a bit more clarity (about the fog, that is), watch this beautiful time-lapse film by Simon Christen, and below that, a short video by KQED’s Quest that digs deeper into the science of coastal fog.
