San Diego weather: Historic rain to start the new year, and more rain chances ahead
Jan 01, 2026
San Diego got a month’s worth of rain to start the new year. More than 2” of rain fell at San Diego’s airport between midnight and early Thursday afternoon, which is more than we would normally get in an entire January (1.98”). It will end up being one of the top 15 rainiest days ever in San
Diego according to data that goes back to 1939.
All that water caused the San Diego River to peak at 12.75 feet this morning, which put it in the upper end of minor flood stage. The river level has dropped since then but will remain in minor flood stage until early Friday morning.
There are still slight chances for light scattered showers for the rest of the afternoon/evening, but the heaviest rain is gone.
Friday is looking drier, and slightly warmer as we get a break between storms. Another, colder system moving down out of Alaska will bring off and on rain chances again starting Saturday evening through the middle next week. Right now, the models show mostly lighter rain, but stay tuned on timing and rainfall amounts as we get closer.
We also have another full Super Moon this weekend for the fourth consecutive months, which will bring King Tides. We’ll have morning high tides around 7’ each morning with Saturday and Sunday morning seeing the highest tides. Each afternoon will have negative low tides.
FRIDAY
Coast: Mix sun/clouds, slightly warmer – upper 60s
Inland: mostly sunny – low 70s
Mountains: mostly sunny – 55
Deserts: mostly sunny – upper 60s
