As of today, San Diego is waking up to clear skies and cool air near the airport at about 54°F, with a quick warm-up on deck. Patchy coastal fog could sneak in through mid-morning, but once the sun breaks through, afternoon highs are expected to climb into the mid 70s.
Afternoon Warmth And A Coastal Marine Layer
Today, patchy fog is expected before 11 AM, followed by mostly sunny skies and a high near 76°F, with light northwest winds around 0 to 10 mph. Inland neighborhoods should heat up faster than the immediate coast, setting up a noticeable temperature contrast from the beaches to the valleys, according to the National Weather Service San Diego.
Foggy Mornings May Slow Commutes
The marine layer is forecast to rebuild each night and hang around through the morning hours through Wednesday, April 8. That means more widespread low clouds and patchy fog along the coast, which can cut visibility on coastal roads and slow early commutes. Morning beach runners and dog walkers should plan on layers, since the gray typically burns off by mid to late morning and gives way to sunny afternoons.
Late-Week Cooldown And Rain Chances
Later in the week, the pattern shifts as a trough approaches, bringing a chance of light showers from Thursday, April 9, through Saturday, April 11, along with cooler daytime highs and breezier onshore winds. Forecasters say ensemble guidance shows most members bringing precipitation Friday into Saturday, with mean totals around 0.25 to 0.50 inch for the mountains and smaller amounts near the coast. Gusty southwest to west winds are possible late in the week, according to the National Weather Service San Diego.
Quick Tips
Build in extra time for morning drives along coastal corridors, and keep a light layer handy for those cool, foggy starts. If you have outdoor plans from April 9 to 11, keep an eye on updates to the forecast and be ready for noticeably cooler conditions by Saturday afternoon.
