San Diego, California – Warmth returns to Southern California just in time for the weekend, as San Diego’s clouds give way to sunshine and classic summer weather beginning Thursday, July 17th. Drivers along I-5 and residents across the county can expect noticeably brighter skies and mild temperatures—ideal for outdoor plans but with a reminder to stay hydrated in the midday sun.
According to the National Weather Service, morning clouds will decrease throughout Thursday, leaving most of San Diego County mostly sunny by afternoon with highs near 73°F. Light west winds will increase to 5–10 mph, providing a welcome breeze along the coast and major corridors like I-8 and I-5. The region’s familiar marine layer will be most persistent in the early hours, but forecasters say clearing is expected by midday. By Friday and into the weekend, the pattern repeats: patchy clouds to start, then sunshine dominating each afternoon, with daytime highs steady in the low to mid-70s.
Residents heading out for summer events or weekend trips should plan for rapid changes from cool mornings to warmer, sunny afternoons. Pack extra water, use sun protection, and watch for reduced morning visibility, especially on coastal roadways. Nighttime lows will remain comfortable, ranging from 64°F to 65°F, with only minor increases in cloud cover after sunset.
Looking Ahead:
San Diego’s five-day outlook stays remarkably steady:
- Thursday: Cloudy early, then mostly sunny, high near 73°F.
- Friday: Gradual clearing, high near 74°F.
- Saturday: Morning clouds, afternoon sun, high near 74°F.
- Sunday: Mostly sunny, high near 73°F.
- Monday/Tuesday: Continued mild, mostly sunny, highs near 74°F.
No major heat spikes or storms are forecast through July 22nd, but check back for any summer weather alerts or updates as conditions can shift.
