**Coastal marine influence and the seasonal marine layer are positioning 82–85°F as the most likely range for the official Los Angeles high on August 25.** Forecasts from the National Weather Service and models emphasize morning low clouds or fog transitioning to sunshine, with southwest winds of 10–15 mph moderating temperatures along the coast and at stations such as LAX. This produces projected highs in the lower-to-mid 80s for beach and airport areas, even as a broader Southern California heat wave pushes inland valleys toward 100°F+. Recent actuals at LAX through late August 2026 have hovered in the upper 70s to low 80s, consistent with typical late-summer climatology (average high near 77°F). The current setup features a strengthening thermal trough inland that enhances onshore flow, limiting extreme coastal warming while allowing modest daytime rises. Model consensus points to little change through the 25th, with any clearing of the marine layer potentially adding 1–3°F but unlikely to exceed the mid-80s in the measurement zone. Traders appear to be pricing this persistent coastal moderation, reflected in the heavy weighting toward the 82–83°F and 84–85°F bins.
