Week-Long Heat Wave Expected To Bear Down On San Diego County

High pressure system over Southern California could bring hottest temperatures of the year

The hottest temperatures of the year are expected to bear down on San Diego County starting at the end of the week as a “very strong ridge of high pressure” anchors over Southern California, according to the National Weather Service (NWS).

How To Stay Safe During A Heat Wave

“We’re expecting this to last from Friday through next week, so it is looking like a toasty 4th of July at this point,” said James Thomas, NWS forecaster.

Inland areas, including Ramona and Alpine are expected to peak in the upper 90s to 100 degrees; temperatures in the lower desert are expected to soar to 115.

Coastal regions could avoid the heat altogether because of a thick marine layer hovering along the shore. Thomas said that should keep coastal temperatures in the mid-70s.

Thomas said winds should not be a factor in increasing the risk of wildfires, but that fire danger remains high because of very dry conditions; rainfall remains nearly 4 inches below normal.

Forecasters are keeping an eye on subtropical moisture in the southeast that could potentially arrive to the region early next week and interfere with the hot temperatures.

“If there are too many high clouds, the hot temperatures could be moderated,” said Thomas.

San Diego County has designated 100 Cool Zones sites to provide air-conditioned settings and relief when temperatures are hot.
