San Diego County is experiencing an extended stretch of record-breaking heat, with daily high temperature records being set across the region. However, a significant pattern shift is on the way, with temperatures expected to plummet by 10 to 25 degrees next week, bringing cooler weather and a chance of showers.

Why it matters

The extreme heat has put a strain on the region's power grid and increased the risk of wildfires, while also impacting residents' daily lives. The upcoming weather change will provide some relief, but also raises concerns about potential flooding or other weather-related issues.

The details

Friday marked the 13th consecutive day of record heat in San Diego, with several locations setting new daily high temperature records. The heat wave has been driven by a strong high-pressure system, though not as intense as the one that set all-time March temperature records last week. Temperatures are forecast to remain 10 to 25 degrees above normal through the weekend, with the hottest days being Friday and Saturday.

  • Friday, March 27, 2026: Daily high temperature records set in Borrego Springs (102°F), Campo (92°F), and Lake Cuyamaca (80°F).
  • Saturday, March 28, 2026: Forecast to be the warmest day of the week, with record highs expected in Ramona, Alpine, Borrego Springs, Campo, Lake Cuyamaca, and Palomar Mountain.
  • Wednesday, April 1, 2026: Expected to be the coolest day of the next week, with highs in the 60s for most of the coast and valleys, 50s in the mountains, and 80s in the deserts.
  • Tuesday, March 31, 2026 - Thursday, April 2, 2026: Chance of showers as a storm system passes to the north, with preliminary forecasts of less than 0.10 inches of rain from the coast to the mountains.
