Triple-digit temperatures headed to Sacramento area. When will weather heat up?
Time to crank up the air conditioners, Sacramento.
After a surprisingly mild summer across the Sacramento region, temperatures are about to heat up.
According to the National Weather Service, triple-digit temperatures are on the horizon for much of Northern California.
“This weekend, highs are forecast to be around 3 to 7 degrees warmer than normal,” the weather agency wrote on X on Wednesday, Aug. 6.
Here’s how hot it will get in Sacramento:
High temperatures forecast for Northern California
The National Weather Service said most of interior Northern California — including Modesto, Stockton and Sacramento — will see “warming temperatures through the rest of the week.”
That means daytime high temperatures of 100 degrees or higher, the weather agency said.
Sacramento residents should also be prepared for moderate heat risk from Friday, Aug. 8, through Sunday, Aug. 10.
How high will temperatures get in Sacramento?
In Sacramento, the hottest weather is expected to hit by weekend, the National Weather Service said.
Maximum temperatures could reach 100 degrees on Saturday and Sunday, according to the weather service.
What’s in the weather forecast for Sacramento?
On Wednesday, Sacramento residents could expect clear, sunny skies and a high temperature of 96 degrees, according to the National Weather Service’s latest seven-day weather forecast.
The overnight low temperature will be 63 degrees.
The high on Thursday should be near 96, while the low will be approximately 63.
Winds could range from 5 to 6 mph on Wednesday and Thursday.
Friday will see a high near 100 and a low around 66, with “light and variable” winds.
Saturday’s forecast calls for a high near 100 and a low around 63.
On Sunday, the high will be approximately 98, with a low around 63.
Who is most at risk in heat?
Starting Friday, Sacramento’s heat risk will be moderate, the weather service said.
The heat risk scale provides a forecast that shows the likelihood of heat-related problems occurring.
The scale calculates how hot it is compared to normal, how long the heat lasts, and whether it’s likely to cause health issues based on data from the U.S. Centers for Disease Control and Prevention.
It ranges from 0, meaning there’s little or no heat risk, to 4, indicating an extreme heat risk.
From Friday through Sunday, the heat risk is projected to be 2, indicating a moderate heat risk.
Moderate heat risk “affects most individuals sensitive to heat, especially those without effective cooling and/or adequate hydration,” the National Weather Service said.
Vulnerable individuals include those who are pregnant, newborns, children, older adults and those with a chronic illness.
These groups are more at risk due to age and conditions that make it difficult to regulate high temperatures.
Why has Sacramento’s summer been cooler than usual?
Sacramento’s summer hasn’t been as brutally hot this year.
As a result of a low-pressure weather system called a “trough,” cooler air has kept temperatures down compared to 2024’s record-breaking heat.
Unlike the summer of 2024 — which had more than 20 days over 100 degrees around this time — Sacramento has only hit 100 twice in the past two months, as of Wednesday, Aug. 6.
Experts previously told The Sacramento Bee that this cooler trend likely won’t last all summer. However, summer weather is hard to predict.
