Afternoon Glow and Peak Temperatures
As the day progresses, the coastal chill will give way to a beautiful, sun-drenched afternoon. High temperatures are projected to reach a comfortable 65°F (18°C) by mid-afternoon. With approximately eight hours of bright sunshine expected today, it is a perfect window for outdoor activities. The UV index is currently rated at a 4 (Moderate), so while the air may feel cool, sunscreen is still advised for those planning extended time at Balboa Park or the San Diego Zoo.

Coastal Alerts and Marine Conditions
For those drawn to the Pacific today, please exercise caution. A High Surf Advisory is currently in effect for San Diego County beaches.
