Extreme Heat Coming to San Diego County’s Backcountry and Deserts This Week

Extreme heat will settle over San Diego County’s inland foothills, mountains and desert areas this week, leading the National Weather Service to urge people to reschedule strenuous activities for the early morning and evening.

The most intense heat will occur Wednesday through Friday, when temperatures will rise into the mid-90s in such communities as Ramona and Escondido, 99 to 100 in Campo near the U.S.-Mexico border and into the 113-to-115 range in Borrego Springs.
