About
Where is the weather actually great right now? Great Weather AI watches the sky with live NOAA satellite imagery and machine-learned fog detection, shows temperatures street by street, and finds the spots that match YOUR definition of great weather.
LIVE FOG MAP
See the Bay Area marine layer exactly where it is right now, detected from GOES satellite imagery by models validated against ground weather stations. Day, night, dawn and dusk. When a higher cloud deck hides the fog, the overcast still shows.
NOW ACROSS THE WHOLE US
Live satellite cloud cover and temperatures for towns across the lower 48, plus temperatures for Alaska, Hawaii and Puerto Rico. See how much cooler the mountains are today, or how the coast compares to inland.
MICROCLIMATES, BLOCK BY BLOCK
Real temperatures for SF neighborhoods and towns everywhere: the Mission and the Sunset are different worlds, and the map shows it.
SCRUB INTO THE FUTURE
Slide the timeline to see clouds and temperatures up to 8 hours ahead, powered by a fused satellite and weather-model nowcast. Future times are clearly marked.
GREAT WEATHER, FOUND FOR YOU
Tell it what great means to you: temperature range, sunshine, wind, how far you'll drive. One tap ranks the closest matching destinations with live traffic drive times, sunniness, and what to do when you get there. Find currently covers the SF Bay Area and Northern California.
HONEST BY DESIGN
No guessing: when the satellite can't see, the app says so. Observations and forecasts are always labeled. Weather data from NOAA GOES, RTMA, HRRR and the National Blend of Models, refreshed every few minutes.
