SAN DIEGO—Temperatures climbed significantly in San Diego County's inland areas Saturday, sending thousands to the beaches while firefighters kept busy fighting small brush fires.
Highs shot into the 80s in El Cajon and Escondido and touched 90 degrees in more outlying locations like Campo, according to National Weather Service records. Borrego Springs, in the desert, hit 105 degrees by early afternoon.
"It looks like today will be the hottest of the (next couple) days,'' said NWS meteorologist Steve Vanderburg.
The warmer inland valleys should still get into the mid- or upper-80s through Monday, Vanderburg said.
Coastal temperatures in the 60s attracted numerous beach-goers who jammed roadways around Mission Beach and Pacific Beach. Westbound Interstate 8 was congested from the state Route 163 interchange in Mission Valley all the way out to the beach areas, according to CalTrans traffic maps.
City lifeguard Lt. John Everhart said there were several "mass rescues'' of swimmers caught in riptides, mainly off Ocean Beach.
There were no serious injuries, he said.
"There were a couple (rescues) in which nearly every lifeguard in the beach was in the water,'' Everhart said.
He said warmer water temperatures are keeping bathers in the water longer than last weekend, when the ocean was chilly.
Four small brush fires broke out in the early afternoon, according to Cal Fire
None of the blazes -- one each in Japatul and Flinn Springs and two in Ramona -- threatened structures and were contained quickly, said Cal Fire's Roxanne Provaznik.
Vanderberg said a low pressure trough will move over Southern California late next week to deepen the marine layer and cool off the temperatures. No rain is associated with the system, he said.
