Marine layer and persistent onshore flow from the Pacific are moderating temperatures across coastal Los Angeles, keeping the August 14 peak in the mid-70s according to the latest National Weather Service and model guidance. Typical August marine stratus and sea-breeze circulation suppress inland heating, with historical downtown and airport observations rarely exceeding 80°F under similar synoptic patterns. The tight market split between 76–77°F (41.5%) and 74–75°F (36.5%) reflects uncertainty in the precise strength of the onshore gradient and any late-day clearing that could allow an extra degree or two of warming. Weak upper-level ridging supports modest daytime heating, but no heat-wave conditions are forecast, aligning with climatological baselines near 78–82°F for the period. Updated model runs and afternoon observations will clarify whether the high settles at the lower or upper end of the favored range.
