Recent National Weather Service and NOAA model guidance for San Francisco on August 24 shows a persistent marine layer with onshore westerly to southwesterly flow, limiting daytime warming and supporting highs mainly in the mid-60s to low-70s. This pattern, typical for late summer along the central California coast, features stratus and fog that moderate temperatures below seasonal averages near 70°F, with limited inland heating influence expected under a neutral to weak ridge. Current observations from KSFO and downtown stations indicate recent days holding in the mid-60s, reinforcing trader focus on the 68–71°F range as the most probable outcome under stable atmospheric conditions.
