SAN DIEGO -  

Hot and dry weather will continue across San Diego County on Saturday.  

"Little change in our offshore weather pattern will bring another very hot day today," the National Weather Service reported Saturday.

Similar temperatures to those on Friday are expected in most areas, the NWS reported.

According to the NWS, temperatures are expected to be higher near the immediate coast, with highs in the 90s to nearly 100 and continuing to be around 105 just inland.

The NWS advised those planning to be outdoors to avoid strenuous activity during the hottest part of the day. Those who will be outside are advised to drink plenty of non-alcoholic, non-caffeinated fluids.

On Friday, the blast of late-summer heat that hit the San Diego area broke several temperature records.

In Vista, the thermometer topped out at 106 degrees Friday afternoon, exceeding the prior milestone high of 99 for the date, set in 1971.

In El Cajon the mercury reached 103, breaking the old record of 100, and Chula Vista sweltered under a high of 93, surpassing the prior Sept. 14 record of 91. Both cities' prior highs came in 1989.

Escondido and Ramona tied their prior record highs for the date -- 103 and 101 degrees, set in 1909 and 1979. At about 5 p.m., the recorded temperature in Mira Mesa was 110 degrees.

"Cooling will begin on Sunday and continue through early next week as high pressure aloft weakens and onshore flow increases," an NWS advisory said.

At Scripps Ranch High School on Friday, at least 70 students had to see the school nurse due to the heat, with some being sent home.

Scripps Ranch High student Cami Lopez told 10News, "It was really hot; it was ridiculously hot. There's no air conditioning; some of the fans were broken."

Student Alex Weber said, "Yeah, there was a kid in my class who got taken out [at] the end of the fourth period because he had heat stroke, I think."

Parents waiting to pick up their students are frustrated.

"Today is shockingly hot. I didn't realize it, but I'm sitting here and it says 105 [degrees] on my car thermometer," Susan told 10News.

Parent Julie Hegeman said, "I think they should have air conditioning. I think they'd have a lot of trouble in this heat."

The school's principal told 10News the school has been pushing for the installation of air conditioners, but the school district says it could be a few years until that happens.

Some chose to beat the sweltering heat at local beaches.

San Diego lifeguards are prepared for a "heavy beach day" all through the weekend, planning to open extra observation towers despite the summer season having ended. Usually, it's time to transition to lower staffing levels, but when the sun beats down as it is, it is best to be prepared.

Cal Fire officials are treating the conditions as extreme fire weather.

Cal Fire Battalion Chief Ray Chaney said, "We're bringing in additional staffing, extra engine companies, bring additional staffing to all support functions so we've got layers of response capability in the event there is a fire."

All air tankers and spotter planes are online, and they'll be ready earlier in the day. Manpower is at full strength, Cal Fire officials said.
