With no improvement in the heat expected inland in the San Francisco Bay Area until next week, much of the region remained warm with above-normal temperatures for the Fourth of July holiday.
According to Paul Heggen, chief meteorologist for KPIX, inland temperatures on Independence Day and Friday will range from 95° to 105°, with highs around the San Francisco Bay reaching the low 80s to near 90°. The region’s coastal communities will remain popular with thermometers only reaching the low 70s.
In warmer inland areas there will be some relief at night with low temperatures between 17 and 27 degrees Celsius.
Wednesday was slightly cooler than Tuesday, with fewer records set for the day. Both San Rafael (100°, breaking the 2001 record of 99°) and Livermore (110°, breaking the 2001 record of 109°) set new records for the day.

Heggen said residents will see a slight drop in temperatures Saturday and Sunday, but it will still be extremely warm inland. He noted that the National Weather Service has extended the Inland Excessive Heat Warning and Bayside Heat Advisory through Wednesday, but speculated that the extension “could be a few days too much (especially for the Heat Advisory).”
However, Heggen said temperatures will remain above average, although the region is trending more towards “hot” than “crazy hot.”
The red flag warning for the East Bay hills and the inland mountains of North Bay has been extended until 9pm Saturday evening.
Residents are advised to drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and stay with family and neighbors. Bay Area counties have opened cooling centers in the region for those who do not have air conditioning.
The increased fire danger caused by warmer temperatures remained evident as crews tackled several large fires in the Bay Area and Northern California, including the Thompson Fire in Butte County forcing approximately 28,000 people to evacuate the area around Oroville, and the Toll fire in Napa County just north of Calistoga.
Thursday morning is the new Major fire broke out in remote area of ​​Stanislaus CountySo far, more than 300 hectares have been burned.
The high temperatures led to the cancellation of a number of daytime festivities on July 4 (in Antioch and Yountville) and fireworks shows (in St. Helena and Healdsburg), but many holidays are continue as planned.
Parks closed Tuesday by the East Bay Regional Park District will remain closed through at least Friday, district officials said. However, swimming facilities and regional parks along the coast remained open during the heat wave. The district will reassess conditions and provide additional information Friday evening. Information on all parks closed due to the warm weather can be found on the EBRPD website.
