Current National Weather Service and ensemble model guidance point to a high near 70–72°F in San Francisco on August 18, driven by a building Pacific high that should limit the marine layer and allow partial afternoon clearing after morning coastal stratus. Onshore flow and the cold California Current continue to moderate temperatures, keeping values close to the August normal of 67–70°F, while any delay in fog burn-off or stronger sea breeze would cap readings in the upper 60s. Trader positioning around the 70–73°F bins aligns with this narrow forecast spread and the historical rarity of coastal extremes exceeding 75°F in mid-August without a strong offshore wind event.
