The Bay Area is simmering as inland temperatures continue to soar into the upper 80s and lower 90s, while coastal areas are starting to experience some respite, according to the latest forecast by the National Weather Service San Francisco, CA. The dense fog creeping along the coast has warranted a Dense Fog Advisory until 10 a.m. this morning, affecting areas from SF south through Monterey Bay and down the Big Sur coast, which could catch drivers by surprise with sudden visibility changes, said the service.

As inland residents feel the heat with peak temperatures today, the weather service advises those in hotter areas to stay on guard, especially populations more sensitive to heat. They should drink plenty of fluids, seek shade, and take necessary precautions during the late morning to early evening hours when the sun's beating hard. Meanwhile, the advisory stated that the fog is expected to make a curtain call tonight, bringing another round of dense fog into Sunday morning, with overnight lows hovering mostly in the 50s.

Looking ahead, the NWS predicts a modest cooling trend early next week as the upper ridge weakens, leading to more seasonal temps throughout the following week. For beachgoers, though, a small, long-period southwest swell might stir up sneaker waves and rip currents this weekend—a hazard for unsuspecting visitors. Although the swell height of just 1-2 feet doesn't hit the criteria for a Beach Hazards Statement, increased beach traffic due to the hot weather increases the risk for those unfamiliar with the ocean's capricious nature.

The foggy conditions don't leave the aviation and marine sectors untouched, as Monterey Bay remains under a Dense Fog Advisory until 10 a.m. Terminal Area Forecasts (TAFs) call for VFR to hold at most terminals, discounting MRY and SNS, which could sway back to low visibility tonight. For mariners, the shallow marine layer keeps things cool along the coast, with breezy northwesterly winds predicted to kick up come Monday. Significant wave heights are set to build at the start of the new week, according to the National Weather Service.
