What’s Driving Today’s Weather?
San Diego’s weather is shaped by the cooling effect of the Pacific, steady winds, and the regular presence of a marine layer. That’s why even the hottest months stay comfortable near the coast: heatwaves are rare, and the marine influence makes for pleasant evenings and mornings.
Safety and Outdoor Tips
While today brings mostly clouds, the forecasted UV Index is very high. If you plan to be outdoors—at the beach, hiking, or biking—wear quality sun protection. Even filtered sunlight can lead to sunburn at midday.
Stay refreshed and hydrated. The gentle breeze will help, but with the sun’s rays peeking through, it’s wise to keep extra water handy.
Key Takeaways
- “Gray” mornings don’t mean a gloomy day: temperatures remain inviting, and outdoor activities are comfortable all day.
- Pack a light layer for the early hours and sunblock for the possibility of clearing skies.
- No rain is expected, making today perfect for outdoor plans.
