Peninsula To Heat Up Amid Bay Area Heat Wave: What To Know

SAN MATEO COUNTY, CA — The Peninsula has been spared from an excessive heat warning this week as a heat wave sweeps the Golden State and western United States, but the southern half of the county will still face a heat advisory.

Nearly all of the Peninsula is forecast to see low heat risk, which means people who are extremely sensitive to the heat should take precautions. A heat advisory is slated to begin at 11 a.m. Wednesday.

The hottest days of the week will be Thursday and Friday. Farthest inland areas and highest elevations will see their Heat Advisory upgraded to an Excessive Heat Warning as temps approach and exceed 100°F! (other areas still in heat advisory)#BayArea #CAwx pic.twitter.com/emoiRM1jm2

An excessive heat warning will be in place for much of the Bay Area from 11 a.m. Thursday to 1 p.m. Friday, which are forecast to be the hottest days of the week. Inland areas could see temperatures in the 90s to 100s, with temperatures up to 110 degrees in the hottest places, according to the National Weather Service.

We think the word got out. And the word is: hot. Temps are increasing later this week. Onshore winds keep the coast cooler, starting Wed. inland areas have rising temperatures. A Heat Advisory has been issued from 11 AM Wed. to 11AM Thurs.

When the heat advisory kicks in, the weather service advises residents to:

• Remain in air conditioning.
• Limit strenuous outdoor activities during the hottest hours.
• Not leave kids or pets in cars.
• Stay hydrated.
• Give extra care to the elderly, kids, pets and plants.
• Be wary of hot pavement when walking dogs.
• Be wary of rip currents at the coast.
• Wear light-colored clothing with a hat.

"Any robust cooling is likely not expected until the weekend," the weather service wrote. "However, that becomes a relative term now that June in the Bay Area is in full swing."

Weather leading into next week is forecast to be warm and dry.

The important thing is to take precautions now. Be sure to check in on those most vulnerable to heat (including pets!) and drink plenty of water. If you have to be outside, use sun tan lotion, take breaks and try and find some shade.#CAwx pic.twitter.com/NAiyKW2gjU
