microclimates.today

Fog tracker, live webcams, and coast-versus-inland temperatures for the whole Bay Area. The marine layer at a glance, refreshed every five minutes.

San Francisco doesn't have weather: it has microclimates, and a forecast for "San Francisco" is wrong somewhere in the city almost every day of the year.

Microclimates shows you the difference and backs it up with raw data that you can see yourself. Per-neighborhood fog and weather, plus live and historical fog views. And the best signal you can get: webcams showing just about every angle of the Bay.

RIGHT NOW One screen that answers the only question that matters before you leave the house: how much colder is the coast, is the fog holding or burning off, and which neighborhoods are socked in. Written out in sentences, not a wall of numbers.

FOG TRACKER GOES-18 satellite imagery of the Bay Area, refreshed every five minutes and archived so you can scrub back through the last two hours, the last day, or the last week. Night microphysics after dark, so the fog is visible at 3am.

WEBCAMS Around thirty live cameras — Mt. Tam, the bridges, the beaches, the coast — stacked one to a screen so you can actually see them.

WEATHER Coast and inland seven-day forecasts side by side, live wind gusts, and the onshore flow that decides which one you get.

NEIGHBORHOODS Every San Francisco neighborhood on one map, colored by temperature, cloud cover, humidity, wind, or dew point. Tap one for its current conditions.

WIDGET Coast and inland temperatures, the fog percentage, and where it is heading — on the home screen or the lock screen.
