For the second time in a single summer, San Francisco is trading fog for unexpected heat — and the second-highest temperatures of the year.
Downtown reached 83 degrees on Wednesday and is expected to remain in the 80s on Thursday. Oakland experienced even higher temperatures of 89 degrees on Wednesday and will feel the same level of heat the next day, says National Weather Service meteorologist Spencer Tangen. The west side near the coast, on the other hand, is seeing temperatures in the 70s.
This week marks the second-highest temperatures of the year, the highest being 97 degrees on June 10 in San Francisco. The warmest temperature of 2018 in San Francisco was 83 degrees on Sept. 20.
“In general, there’s a slow upward trend in the warm days,” Tangen says. “It’s some of the warmest temperatures we’ve seen in a while.”
Which begs the question: isn’t August supposed the month where San Francisco is wrapped in even more fog?
Temperatures should cool down to about 70 degrees in San Francisco on both Wednesday and Thursday around 7 p.m., as the pressure coming from the southeast part of the country lessens. Friday will reach the mid to upper 70s, or lower to mid-80s in Oakland before temperatures settle into 60s.
In other words, the fog will return over the weekend but some warmer weather may return this time next week. Fall is also around the corner, which brings higher temperatures for the city.
It’s still better in San Francisco than other surrounding areas. Inland cities of the Bay Area and the Central Coast are in the midst of a heat advisory, with temperatures reaching upwards of 100 degrees in places like Walnut Creek.
Tangen recommends staying indoors, finding air conditioning, limiting strenuous activity outdoors, and drinking plenty of fluids. The San Francisco SPCA cautions that if the pavement is too hot for hand after 10 seconds, it’s too hot to walk your dog there — and definitely too hot to leave them in the car.
