Slightly cooler but still sweltering conditions are expected in San Diego County Tuesday as the region’s record-breaking heat wave goes into a fourth day.
On Monday, the torrid conditions set daily heat records across Southern California, including in San Diego County. Oppressive highs of 118 degrees in Borrego Springs and of 106 degrees in Escondido each topped by 2 degrees previous records for June 20, set in 2008 and 1973, respectively. A 109-degree high in Ramona and of 110 degrees in Campo exceeded the previous records of 106 and 105, both set in 2008, and a 107-degree high in El Cajon was 13 degrees higher than the prior high, set nine years ago.
Records were also broken in Chula Vista with a high of 91 degrees and on Palomar Mountain at 96 degrees. A 107-degree high Monday in Alpine tied a temperature milestone from 1973, according to the National Weather Service. Records were broken Sunday as well.
An excessive heat warning for the mountains and deserts is set to expire at 8 p.m. Wednesday.
In the forecast for Tuesday — the second day of summer — temps were somewhat lower, but still above average, with highs of 73 to 78 degrees at the beaches, 81 to 86 degrees in inland coastal areas, 83 to 88 degrees in the western valleys, 88 to 93 degrees near the foothills, 91 to 98 degrees in the mountains and 109 to 114 degrees in the deserts.
“High pressure is slowly shifting to the east and cooler conditions have developed along the coast and in the valleys, however it will continue to be excessively hot for the inland mountains and deserts through at least Wednesday,” according to the weather service.
Forecasters advised the public to avoid potentially serious heat-related ailments by staying well-hydrated, avoiding unnecessary outdoor labor and checking on neighbors and relatives — especially those with health conditions and who lack air conditioning.
Authorities also warned against leaving children, seniors or pets in parked cars, which can quickly become death traps in high heat.
