June 20, 2017 (San Diego’s East County) – Tuesday’s blistering heat wave set a new county record. In Ocotillo Wells, the temperature reached 124 degrees—the hottest temperature ever recorded in San Diego County, according to Noel Isla with the National Weather Service.

Borrego Springs recorded 122 degrees, tying a previous record set exactly one year ago on June 20, 2016.  A reader with a weather station in Boulevard informed us he measured 102 degrees, while temperatures in Ramona, Alpine and other mountain areas reached the mid-90s. 

In case you’re wondering, the hottest temperature record ever recorded on earth occurred in Death Valley, California in July of 2013, when the mercury hit 134 degrees, shattering a world record formerly set 90 years earlier in Libya.

By contrast, San Diego’s coastal areas were balmy by comparison, with high temperatures in the high sixties to low seventies.

An excessive heat warning for San Diego County’s deserts through  Monday evening, with a heat advisory issued for the mountains and inland valley areas. 

So drink plenty of water to stay hydrated, don’t leave children or pets on hot cars even for a short time, wear loose-fitting clothing to keep cool, and check out air conditioned locations designated as county cool zones at
