Forecast models from the National Weather Service and ensemble runs project a typical mid-August pattern for San Francisco, with the daily high likely settling near 70–72°F due to persistent onshore flow and a stable marine layer off the Pacific. This coastal moderation, driven by the cold California Current and afternoon sea breezes, keeps extremes rare, aligning with historical August averages of 69–71°F at official stations. The narrow spread between leading bins reflects modest uncertainty in boundary-layer mixing and exact timing of any fog burn-off, which can shift the peak by 2–3°F. Recent model consensus shows little deviation from climatology, with no strong ridge or offshore flow expected to push readings into the mid-70s or higher. Traders are watching the next NWS update for refinements in wind and cloud forecasts ahead of the August 11 observation window at San Francisco International Airport.
