Forecast San Francisco is the definitive portal for the Bay Area's weather and climate — built to make the official National Weather Service forecast fast, clean, and highway-clear across the eight counties around the bay, from the Golden Gate and Oakland out to Walnut Creek and Livermore, north through Marin to Santa Rosa and the Napa Valley, and east along I-80 to Fairfield and Vacaville.
No place in America packs more microclimates into an hour's drive. The fog pours through the Gate while Walnut Creek runs thirty degrees warmer; the Diablo winds turn the hills into October fire country; and the winter atmospheric rivers stall over the Coast Range and put the creeks over their banks. Forecast San Francisco is being built to tell that story — county by county, corridor by corridor.
The look borrows from the American Interstate system — the reflective paper, the green guide signs, the blue service signs, the brown recreation signs, and the red-white-and-blue route shields — set in Overpass, the typeface drawn from the Highway Gothic lettering on those signs. As a metro site its hero is the eight-county bay, in a Golden Gate orange accent for the bridge rising out of the fog, on pale bay-water blue — its own note in the network.
Forecast San Francisco is the metro zoom-in for Forecast California. The two are companions — the city and the state — and both are part of the wider Forecast network.
