100-degree temperatures are headed to Sacramento area. How long will the heat wave last?

Triple-digit temperatures are expected to bake the Sacramento region next week, just in time for the Fourth of July.

The National Weather Service is predicting high temperatures of 100 degrees to start Monday.

The heat wave could last more than three days, the forecast shows.

Here’s what to know:

What’s in the weather forecast for Sacramento?

Sacramento was expected to be sunny with a high temperature near 91 degrees on Thursday with an overnight low around 59 degrees, according to the National Weather Service’s seven-day forecast.

Friday will have a high near 95 and a low around 61.

Temperatures will steadily increase in the following days, according to the forecast.

The weather service said the hottest days will be Tuesday and Wednesday, when highs are expected to reach around 105 degrees.

Eric Kurth, a meteorologist with the National Weather Service, said the agency is also predicting triple-digit heat on Thursday, July 4.

The high could reach 102 degrees on Independence Day, Kurth said.

When will the heat wave end?

While the weather service is confident it will be very hot next week, Kurth said, it’s too early to predict when the heat wave will end.

“Just be prepared for some unusually hot weather,” he said.

How to survive hot weather

Generally, you should head to air-conditioned spaces when high temperatures hit.

If you don’t have a cooling unit at home, you can go to a mall, cooling center or another public space, experts said.

“The gold standard … is really getting to an air-conditioned space,” Dr. Sheri Belafsky, a UC Davis Health physician, told The Sacramento Bee in 2023. “People in urban areas … can be particularly impacted by high heat, or if they’re an apartment dweller, they really don’t have very good ventilation.”

If you don’t have access to a cooling unit or need to stay home, experts recommend taking a cold shower or bath.

You should avoid vigorous physical activity, wear lightweight clothing and drink water.

You should stay away from caffeinated drinks as they can dehydrate your body.
