San Francisco’s warm weather Monday and last weekend didn’t shatter any records, but residents were still left uncomfortably hot.
The City saw a high of 92 degrees Sunday, with an expected high Monday of 93 degrees, said Anna Schneider of the National Weather Service. The normal average high is 70 degrees for this time of year.
The heat wave is due to a strong high pressure system over the area with offshore air flow, allowing little relief from the cooler ocean waters, according to Schneider. However, the City is experiencing fewer hot spells than last year.
The Bay Area Air Quality Management District issued Monday its 25th Spare the Air Alert for smog this year, tying a record high number of such alerts in 1996.
“This latest heat wave is converting car exhaust from our crowded highways into unhealthy smog,” Jack Broadbent, executive officer of the air district, said in a statement. “Unless we reduce the number of cars on roads we will continue to experience unhealthy air when temperatures rise.”
He encouraged residents to consider carpooling, biking, walking or taking public transit to work.
High pressure weather systems typically produce less “mixing” of the air, Schneider said. This makes it feel hotter and — combined with air pollution — makes it difficult to breath. Schneider advised people to limiting their outdoor activities, staying cool, drinking plenty of water and avoiding leaving kids and pets in cars.
“If it is too hot for your bare feet, it is too hot for a dog’s bare paws,” Schneider said. Those who take pets for a walk are advised to keep the activity short and head for grass because dogs and other animals can get burns on their paws.
Relief is in sight with temperatures expected to cool off by mid-week, and temperatures returning to normal ranges by the end of the week with highs in the upper 60s.
