Latest National Weather Service guidance and ensemble model runs indicate a marine layer will persist along the Southern California coast into August 11, moderating the daily maximum at the official Los Angeles International Airport station near the seasonal normal of 76–78°F. Light onshore flow and low-level stratus limit daytime heating, keeping the highest temperature in the 76–79°F range that currently commands over 76% combined implied probability. Warmer outcomes above 80°F would require a stronger offshore or upper-level ridge influence to erode the marine layer, an evolution not strongly supported in the most recent model consensus. Traders are weighting the tight 76–77°F versus 78–79°F bins because small differences in cloud cover timing or wind direction can shift the peak by 1–2°F, consistent with historical August variability at the coastal site. Updated short-range forecasts and afternoon observations tomorrow will provide the final resolution data.
