As Bay Area residents revel in unseasonable warmth, the National Weather Service San Francisco advises caution with a Beach Hazards Statement in effect through Wednesday morning. Despite the tempting sunny skies, the Pacific waters are reportedly brisk, ranging between 51°-57°, accompanied by risks of sneaker waves and rip currents. The National Weather Service reminds beachgoers that the ocean remains quite inhospitable while it may be warm on land.
Yesterday, several locales across the Bay Area and Central Coast shattered previous record highs, with interior Central Coast regions touching the 90s. The high temperatures will persist for another day, with forecasted highs in the mid to upper 80s and isolated spots potentially reaching the low 90s. However, this heatwave is set for a timely demise as "seasonal temperatures and rainy weather return midweek," the NWS San Francisco statement noted.
Further details from the NWS San Francisco's Area Forecast Discussion indicate that today's temperatures may edge even higher than those recorded yesterday, with a subtle onshore wind transition determining the eventual peak temperatures. But as we look ahead, cooler weather looms, heralded by a weak system that promises to steer us back to the familiar climes of mid-60s to low 70s. With this system, expect a dusting of rain across the Bay Area and the possibility, albeit low, of thunderstorms midweek.
For mariners, the shifting weather patterns bode a transition from light northerly breezes to moderate to fresh southerly winds by mid-Wednesday. "Seas will flux between moderate and rough through Wednesday," according to the National Weather Service forecast discussion. Beyond that, conditions out at sea are predicted to nosedive by Thursday, driven by fresh west-to-northwest breezes and choppy seas, setting a somewhat unsettling stage through to next week.
