San Diego woke up to a textbook chamber-of-commerce kind of day, with clear skies and a cool start in the mid-50s. San Diego International Airport checked in around 55 to 56°F early this morning, and the rest of the day is set to stay dry and sunny. Look for an afternoon high near 70°F and an overnight low close to 56°F, with the marine layer mostly holding off until after sunset.
Afternoon Breezes and Coastal Rattles
With plenty of sunshine, temperatures will climb into the upper 60s to around 70°F. Southwest winds will generally run 0 to 15 mph, but by late afternoon, some spots could see gusts up to 25 mph. That could make the shoreline feel a bit brisk and might send unsecured patio chairs scooting across decks in more exposed areas, according to the National Weather Service San Diego. There is virtually no chance of measurable rain through Wednesday.
Mountain and Desert Gusts Kick Up Thursday
By Thursday, a low-pressure system moving inland will tighten the onshore flow. That will cool inland areas by a few degrees and crank up southwest-to-west winds across the higher terrain. Gusts of 35 to 45 mph are expected across mountain passes and desert slopes. Drivers heading through the passes and hikers in the foothills should secure loose gear and be ready for sudden, strong gusts. Clouds will increase late Wednesday night into Thursday morning, but most of the coast is still expected to stay dry.
Offshore Flip Friday and a Mild Weekend Boost
On Friday, the pattern turns around, with an offshore breeze bringing northeast gusts along the coastal slopes. That will nudge temperatures up a bit at the shoreline and in the valleys, while the deserts cool slightly. Highs should push into the mid-70s Friday and hold there into the weekend, with inland areas running a few degrees warmer, and Sunday is expected to be several degrees above average, a fairly typical early spring rebound. Outdoor plans on Saturday or Sunday look good to go, though layers will still be your friend in the morning and evening.
What to Watch the Rest of the Week
For now, there are no watches, warnings, or advisories in effect for San Diego County, and forecasters do not expect hazardous marine conditions through Saturday. If you are planning to drive through mountain passes later this week, check local road conditions and the National Weather Service for updated wind statements before heading out.
