Northern California to see another heat wave early next week. What’s different from last time?

The Sacramento Valley and Sierra foothills will experience more triple-digit heat early this week in yet another mid-summer heat wave.

But here’s some good news: This sweltering span is predicted to be much shorter and not a record-breaking couple of days, said Dakari Anderson, a meterologist at the National Weather Service’s Sacramento office.

The weather service issued a heat advisory beginning at 11 a.m. and ending 11 p.m. Wednesday as temperatures are expected to rise about 10 degrees higher than what is typical for this time of year, Anderson said.

“With this next run of warm temperatures, we have major heat risk developing throughout the Valley with localized areas of extreme heat risk, which is our highest category,” Anderson said.

Extreme heat risk advisories were issued for more elevated parts of the region, including foothill spots east of Chico and Yuba City.

Highs in Sacramento will reach 103 to 110 degrees. While these temperatures are not nearly as high as recent heat records, the weather service warned that people should still prepare for heat related illnesses and outdoor activities being impacted.

Overnight temperatures will reach the low 70s in Sacramento, and the region is supposed to be milder by Friday, when the predicted high is 93 degrees.

South Lake Tahoe will see a similar spike in hot days, but with temperatures only reaching the mid 80s. Lows at night will go down to 60 degrees, according to the NWS forecast.

Hot days have already plagued the region throughout the past month, when a heat wave broke the record for the hottest 20 days in Sacramento’s history, and they may continue throughout the rest of the summer. The hottest day on record in Sacramento was in September of 2022.

“It should be considerably shorter, we’re only hoping it will be those three days ending that Wednesday night, and then we’re not going to see as warm of temperatures,” Anderson said.
