**Marine layer and onshore flow are keeping coastal Los Angeles temperatures suppressed, positioning the highest temperature on August 9 in the upper 70s.** Official National Weather Service point forecasts for the Los Angeles area on the upcoming Sunday show patchy dense fog through mid-morning followed by gradual clearing, with a high near 77°F under light southwest winds. This pattern aligns with the market’s strong 57% implied probability on 78-79°F, reflecting typical August marine-layer dynamics that limit daytime heating along the coast and coastal valleys. Slightly warmer outcomes (80-81°F at 22.5%) remain plausible if the low clouds break earlier or onshore flow weakens modestly, while lower bins capture limited downside risk from persistent stratus. Historical August climatology for downtown Los Angeles centers on highs around 84-85°F, but the current setup favors below-normal readings due to the strong marine influence and lack of offshore wind or high-pressure ridging that would otherwise drive heat. No major forecast shifts have emerged in recent model runs, supporting the tight clustering around the 78-79°F range ahead of final observations.
