San Jose is starting today mostly clear and headed for the upper 70s this afternoon, with a forecast high near 786 degrees. Low clouds and patchy fog are likely in the usual low-lying spots early on, but skies should open up by midday for bright, sunny afternoons. Memorial Day looks a touch cooler before a gustier system muscles in on Tuesday.

Morning Fog, Sunny Afternoons

A deep marine layer sitting around 2,000 feet will keep low clouds and patchy fog clinging to shoreline areas and valley low spots through the morning. Most inland neighborhoods should shake off the gray, clear to sunshine, and climb into the upper 70s.

Tomorrow (Memorial Day), expect more of that morning murk. Patchy fog is likely before 7 AM, then skies turn mostly sunny, with a high near 756 degrees and a breezy west wind gusting to around 18 mph. By Tuesday, an inside-slider pattern will shove strong northerly winds into the region, with gusts of 30340 mph possible along exposed coastlines, ridgelines, and through gap passes. There are currently no watches or warnings in effect, according to the National Weather Service.

Plan For Fog And Gusts

Morning commuters today and tomorrow should be ready for reduced visibility near creeks and along bayfront routes, where fog tends to pool. Give yourself some extra time for those early trips so you are not white-knuckling it through the mist.

Boaters and shoreline visitors should check local marine notices before heading out, since the strongest gusts are expected Tuesday afternoon and could kick up choppy waters. 

Quick Take

Bottom line: foggy starts, sunny afternoons, a mild Memorial Day, and a gusty Tuesday, so adjust outdoor plans if you can. If you have a boat trip booked, consider moving it earlier in the week or holding off until the winds calm down.
