San Diego Breaks Heat Records as Temperature Spike Ends

SAN DIEGO, Calif. (March 29, 2026) – San Diego County has been sizzling, breaking temperature records across the region on Sunday. The mercury soared to unprecedented highs as several locations recorded temperatures significantly above average, marking a historic weather event in the area. However, relief is expected as weather patterns shift towards more typical temperatures early next week.

Record-Breaking Temperatures

On Sunday, cities throughout the county experienced an unusual heat wave, with temperatures soaring up to 25 degrees above the seasonal norm. Notable records were set in various locations:

• Riverside: 94°F (previous record 93°F in 2004)
• San Jacinto: 92°F (previous record 91°F in 2015)
• Escondido: 93°F (previous record 89°F in 1898)
• Idyllwild: 78°F (tied with the record of 78°F in 2015)
• Lake Cuyamaca: 79°F (previous record 75°F in 2015)
• Campo: 92°F (previous record 86°F in 2015)
• Palm Springs: 98°F (tied with the record of 98°F in 2015)
• Borrego Springs: 97°F (previous record 95°F in 2015)

The extreme temperatures served as a reminder of the ongoing climatic fluctuations that have become more prevalent over the years. Residents were urged to stay hydrated and minimize outdoor activities during peak hours as the heat was felt throughout the region.

A Promising Cool Down

The intense heat is forecasted to give way to cooler temperatures beginning Monday. A low-pressure trough is expected to sweep into the area, bringing daytime highs closer to the seasonal average. While the coastal areas can expect temperatures in the 60s to 70s, the desert regions are predicted to see highs dipping to the 80s, providing much-needed respite from the earlier sweltering conditions.

This change in weather will not only aid in cooling off the area but will also introduce a chance of rain, beginning as early as Tuesday night. While projections indicate that rain chances may diminish, weather experts suggest residents can anticipate light sprinkles associated with this shift.

Expect More Clouds Than Sun

As the weather system arrives, mostly cloudy skies are expected to take over the week, giving the sun a much-needed break. Residents who have adjusted to this spring's warm and sunny days will find it a stark contrast. Weather patterns will likely shift again heading into the weekend, with temperatures projected to gradually increase once more.
