Official forecasts from the National Weather Service project a high near 75°F for San Francisco on August 9, driven by the persistent marine layer and onshore sea breeze that typically caps coastal highs in the low-to-mid 70s during summer. This pattern reflects the cool Pacific influence and frequent fog or low clouds, consistent with August climatology averaging 69–70°F. Recent model runs show minimal warming signals, keeping probabilities concentrated on outcomes at or below 77°F as traders weigh the low likelihood of a stronger offshore flow or heat surge reaching the immediate coast.
