Current forecasts from the National Weather Service and ensemble models indicate a San Francisco daily maximum near 70–72°F at official stations like KSFO, driven by persistent marine layer stratus and moderate westerly onshore flow that limits daytime heating. This positions 70–71°F and 72–73°F as closely matched leaders, reflecting genuine uncertainty in exact clearing timing and wind strength rather than a strong consensus. Historical June climatology shows average highs of 67–70°F with frequent coastal moderation, making higher outcomes unlikely without unusual offshore flow. Traders weigh the latest model runs showing slight warming potential against the risk of thicker fog keeping readings at the lower end of the range.
