Dangerously high temperatures set a record: When will it cool down?

Monday’s extreme heat reached 101 degrees in Santa Rosa — setting an all-time record for the day and recording the first triple‑digit scorcher in the city since fall 2017, according to the National Weather Service.

The last time it was almost this hot on June 10 was the 100-degree reading in 1921. And it’s not been as hot as it was Monday since Santa Rosa recorded 100 degrees on Sept. 10, 2017, during a spate of blistering heat a month before the historic Tubbs fire burned a wide swath through the Santa Rosa area.

Despite the sweltering day in the city, Healdsburg topped it with a Monday high of 104.

The heat blast that started over the weekend has peaked, weather service senior meteorologist Steve Anderson in Monterey said, and “things should slowly start cooling off through the week and we should be back to normal by Friday.”
