Mountain View, CA Weather Forecast
Santa Clara County, California
Seven-day outlook
48–70°F across the weekThe week runs between 48° and 70°, with today the warmest day of it. There is no real trend across it: one day looks much like the next. Every day in the outlook stays dry.
Forecasts come from the National Weather Service's own computer models, and current conditions from the nearest reporting weather station. Both are served through the weather API. A forecast is guidance, not a warning, and anything the Weather Service has actually issued is on the live map.
The written summaries on this page are generated from the forecast data above, not by a meteorologist. Each sentence is a reading of the same numbers you can see, and no forecaster has reviewed them.

How well can the network see Mountain View?
The nearest Doppler radar is KMUX (San Francisco, CA), 20 miles to the SSE. A WSR-88D's lowest routine scan sits half a degree above horizontal, and the earth curves away beneath it, so by the time that beam reaches Mountain View its center is about 1,100 ft above ground. That is about as close as radar coverage gets in the United States: the lowest scan is still near the ground when it reaches Mountain View, so low-level rotation and the leading edge of a gust front show up on it. Mountain View is closer to its radar than 85% of US cities.
The closest instrument actually measuring the air is KNUQ · Moffett Fed Airfld on the ASOS/AWOS network, 1.7 miles away. Close enough that its readings are, for practical purposes, the conditions in town.
Beam height is the standard 4/3-earth approximation for the 0.5° scan and assumes normal refraction; it is where the center of the beam is, not its edges, and unusual temperature profiles bend it. Radar siting from the NWS WSR-88D network, station positions from the California observing network as of this build.
