San Franciscans are soaking up some notably warm weather today, as the National Weather Service Bay Area reports that the region will experience "warm and sunny" conditions with temperatures across the 60s and 70s. Today could mark the warmest day of the year to date or, at the very least, tie with previous high temperatures for 2025. This update comes courtesy of a social media post from the NWS Bay Area.

Our bayside bubble of warmth results from upper-level ridging building into the area, ushering in mostly sunny skies and a gentle climb in the mercury, particularly in Bay Area valleys. The National Weather Service San Francisco further detailed this morning that inner valleys could see temps inch into the low to mid-70s, while coastal and mountainous areas generally enjoy highs in the 60s. While the ridging is expected to be nudged east late Wednesday into Thursday, bringing increased cloud cover and maintaining lows in the 40s, Thursday could echo today's warm pattern if enough sunshine breaks through the clouds, per the National Weather Service.
Looking ahead, the forecast suggests that while chances of precipitation have dwindled for Thursday and Friday, a substantial pattern shift over the weekend may well change that. The NWS San Francisco notes, "This will bring several chances for rain and active weather." Notably, rain chances look more promising, arriving late Saturday into Sunday as an upper-level trough inch closer from the Pacific, possibly bringing with it not just showers but the chance of a few rumbles of thunder.
For those with an eye on marine conditions, the same advisory highlights a gentle to moderate breeze over the water persisting through the rest of the workweek, with a moderate northwest swell expected to roll in late Thursday. Weekend showers are on the agenda for our coastal expanse, too. The High Surf Advisory and Beach Hazards statement regarding beach-going was lifted early this morning. However, with buoys charting 9 to 14-foot waves, a cautious stance is still advised for those heading to the oceanfront.
