San Diego Heat Records Expected Before Cooler, Wetter Pattern

Why this matters: This drastic weather shift can impact public health, increase fire risk, and disrupt outdoor activities. Residents should prepare for both extreme heat and subsequent rain.

San Diego County is set to experience a tale of two weather patterns this week. The beginning of the week will see temperatures soaring well above seasonal averages, driven by easterly winds and low humidity. According to the National Weather Service (NWS), some areas could see temperatures 12-17 degrees above normal for this time of year. Ramona and Palomar Mountain are specifically expected to break records. This heatwave poses a moderate heat risk, particularly in the western valleys.

However, this warm spell will be short-lived. By midweek, a cold storm system will sweep through the region, bringing a significant drop in temperatures and a chance of showers. The most significant cool-down is expected by Thursday, with rain likely to persist through Saturday. Coastal areas will see temperatures in the upper 50s to mid-60s, while mountain communities could drop into the 40s, with overnight lows in the 30s.

The combination of low relative humidity and easterly winds also creates elevated fire weather conditions for the foothills and eastern valleys in San Diego and Riverside Counties. Residents in these areas should be particularly cautious.
