Summer weather is making its last stand this first week in September, filling the Bay Area with sweltering temperatures, light breezes and muggy air.
After a Labor Day filled with cool breezes and 70-degrees skies, the change seems unusual. But its normal for warmer weather to resurge for a few days before sinking into the typical autumn weather, according to National Weather Service meteorologist Roger Gass. “It basically goes back to near normal this time of year,” Gass said. “Nothing too eventful beyond that.”
Residents in Livermore and Concord can expect to sweat under 100-degrees skies Tuesday through Thursday with gentle 8 mph wind gusts.
Those in South Bay cities including San Jose and Santa Clara, can look for the thermometer to move three to four ticks above 90 degrees and feel slightly faster 11 mph breezes. Along the coastal area from San Francisco to Palo Alto, cities will shift into the upper 70s to lower 80s.
The Bay Area Air Quality Management District warns residents to stay indoors during the hottest part of the day on Tuesday and Wednesday as the area experiences unhealthy concentrations of ground-level ozone pollution. High levels of pollution are harmful to breathe, especially for young children, seniors and those with respiratory and heart conditions, the district states.
