Official forecasts from the National Weather Service and AccuWeather project a San Francisco high near 70–72°F on August 12, driven by a persistent marine layer and steady onshore flow from the cool Pacific that caps afternoon warming and favors the market's leading 70–71°F bin. Typical August climatology centers around 69°F at downtown and airport stations, with model guidance showing limited potential for significant deviation absent a major shift in the inversion or wind patterns. Recent observations confirm the marine stratus influence continuing to moderate conditions along the immediate coast, consistent with historical patterns where the Bay Area remains far cooler than inland regions. Resolution will depend on the official maximum recorded at the primary NWS station, with any late-day clearing or wind changes representing the main variables that could nudge readings into adjacent bins.
