San Diego started Thursday on the calm side, waking up to clear skies and temperatures in the low 50s at San Diego International Airport (about 52°F). Afternoon highs are expected to top out in the mid-60s under partly sunny skies with a north breeze around 5 to 15 mph. That quiet pattern holds for a few days before flipping late this weekend, when a stronger system moves in and brings the best shot at widespread rain and mountain snow early next week.
Weekend Outlook
Friday and Saturday are lining up to be classic mild winter days, mostly sunny and comfortable, with highs around 66 to 68°F inland and cooler temperatures along the coast. There is a slight chance of showers over the mountains Friday afternoon, but most neighborhoods should stay dry through Saturday. By Sunday, clouds increase and the atmosphere starts to ramp up, with low chances for light rain developing in the afternoon.
What to Expect Monday (Presidents' Day)
According to the National Weather Service San Diego, a large upper-level low is forecast to move inland from Sunday night through Tuesday, putting Monday, Feb. 16 (Presidents' Day), in the prime window for heavy rain and significant mountain snow. Forecasters highlight an elevated chance of at least 0.5 to 1.0 inches of rain in the mountains and a good probability of several inches of snow above roughly 5,000 to 6,000 feet. Gusty southwest to west winds are expected over coastal waters, mountains and deserts, and hazardous marine conditions are possible from Sunday night into Monday.
Prepare and Plan
City crews are already clearing storm drains and making limited empty sandbags available at recreation centers. Residents are encouraged to sweep gutters, secure loose outdoor items and move vehicles out of low-lying parking lots before high tides and heavier rain arrive. To report non-emergency flooding or street problems, use the Get It Done app or call 619-527-7500. For information on sandbag locations and additional tips, visit the City of San Diego storm preparedness page.
Travel, Marine And Safety Notes
Drivers should plan for slower commutes on Monday and Tuesday, since localized flooding and standing water can strand vehicles and delay transit, especially near burn scars and in low-lying coastal streets. Do not attempt to drive through flooded roadways, and build in extra time for trips. Boaters should be ready for deteriorating conditions from Sunday night into Monday. Lifeguards and marine officials will post beach alerts if surf or tides create hazardous conditions.
Quick Take
Enjoy the mild, mostly dry weekend, but treat Monday, Feb. 16, as the first real storm window: heavy rain and mountain snow are likely. This space will be updated as any watches or warnings are issued.
