San Diego Faces Extreme Heat and High Surf Advisories

San Diego, CA, July 30, 2026 —

San Diego County is bracing for significant weather changes as multiple advisories have been issued across the region. An extreme heat warning is currently in effect for the deserts and mountains, expected to last until Sunday evening. This warning signifies dangerously high temperatures that could pose a risk to public health.

Following this, a heat advisory is scheduled to begin for the county’s valleys and coastal areas. This advisory will be in place from Friday through Sunday, indicating that temperatures will be uncomfortably warm and potentially hazardous for individuals without access to adequate cooling.

In addition to the heat, the coastal areas of San Diego are also under a high surf advisory. Residents and visitors can expect waves ranging from 5 to 8 feet, with occasional sets reaching up to 9 feet. This advisory is in effect until Saturday afternoon and is a result of the strong ocean conditions.

The elevated surf activity has also prompted a coastal flood advisory for low-lying coastal areas. This advisory warns of potential minor flooding during periods of high tide, particularly in areas that are typically susceptible to inundation. Authorities advise caution for anyone planning to visit or travel near the coast during this period.
