San Diego County has seen a remarkable 14 consecutive days of daily temperature records being tied or set, with 143 new records in the month of March alone. Saturday saw 9 new records, and more are expected on Sunday, with the entire county running 10-20 degrees above average. Relief is in sight, however, as clouds and cooler temperatures are forecast to move in early next week.

Why it matters

This extended period of extreme heat is highly unusual for the San Diego region, and is indicative of the growing impacts of climate change. The record-breaking temperatures are straining the power grid, increasing the risk of wildfires, and putting vulnerable populations at risk of heat-related illness.

More records are expected on Sunday in Ramona, Alpine, Palomar Mountain, Lake Cuyamaca, Campo, and Borrego. Temperatures across the entire county have been running 10-20 degrees above average, with the coast reaching highs of 72-84°F, the inland areas 85-89°F, the mountains 77-90°F, and the deserts 95-100°F.

“Wow.”

What’s next

Cooler temperatures and more cloud cover are expected to move in early next week, providing some relief from the extended heat wave. However, the return of Santa Ana winds on Friday could bring additional fire risk to the region.

The takeaway

This prolonged period of record-breaking heat in San Diego is a stark reminder of the impacts of climate change, and the need for the region to prepare for more extreme weather events in the future. Local officials and residents will need to remain vigilant in monitoring the situation and taking steps to protect vulnerable populations.
