Southern California heat wave brings record temperatures to these areas

SAN DIEGO (FOX 5/KUSI) — As a late-summer heat wave scorched communities across Southern California, a handful of places set new record highs with its triple-digit temperatures.

Ramona, Santa Ana, Anaheim and Newport Beach all soared to new records for their hottest day in history on Friday, according to the National Weather Service.

Out of all of those neighborhoods, Ramona reported the hottest peak temperature with 114 degrees, NWS said. The eastern San Diego County's previous record of 112 degrees was recorded four years ago, in 2020, during another historic heatwave in early September.

However, Anaheim, located just up the Interstate 5 in Orange County, saw the biggest change in its hottest-day-in-history temperatures. According to NWS, Friday reached 112 degrees, up seven degrees from its previous record of 105 that was also set in 2020.

The latest scorcher set in over Southern California on Wednesday, prompting excessive heat warnings and heat advisories for much of the region.

Large stretches of San Diego County topped out above 100 degrees during the heat wave's third day, with most of the region nearing — but not surpassing — other record highs.

Forecasters are expecting the heat to stick around into early next week before easing up around Tuesday. Both the heat advisory and excessive heat warning are set to expire in San Diego County on Monday at 8 p.m.

Inland communities, who are impacted by the excessive heat advisory, could see peak temperatures anywhere from 100 to 108 degrees while it remains in place, NWS said. This includes places like El Cajon, Julian, Borrego Springs, Escondido and Campo among others.

Meanwhile, costal communities from the border up to Oceanside could see highs in the mid-80s to upper 90s, according to NWS.

As the heat wave continues, residents are encouraged to take precautions to prevent heat-related illness, including staying in air conditioned areas whenever possible, avoiding strenuous activity during peak hours, drinking plenty of water and wearing loose, light-colored clothing.

For those who do not have regular access to air conditioning, "cool zones" are available throughout the county at publicly-accessible sites, like libraries and recreation centers.

A list of cool zones can be found on the county's website. Residents can also call 2-1-1 to receive more information.

Health officials also urge people to watch for the signs of heat exhaustion or stroke, including a high body temperature, changes to skin, a fast and strong pulse, headache, dizziness, nausea, confusion, and loss of consciousness.
