San Diego County’s 10-Day High Temperature Record

Welcome to another heat wave. Triple-digit temperatures on tap for Southern California.

The daily high in San Diego is expected to top 103 degrees on Monday afternoon, according to the National Weather Service. Thursday’s high of 108 degrees will be its warmest on record. That may be low.

The city’s high is expected to reach 108 degrees on Thursday, marking the 10th day in a row with highs topped out at or above 90 degrees.
