**Forecast models and official National Weather Service guidance point to a high in the upper 80s to low 90s°F for Los Angeles on August 29, driven by a post-heat-wave cooling trend under strengthening southwest onshore flow.** After several days of extreme heat with highs near or above 95–100°F, increased marine-layer influence and diurnal sea-breeze circulation are expected to moderate temperatures, keeping the peak below the recent peak but still well above the ~77°F late-August climatological average at Los Angeles International Airport. Key variables differentiating the tightly bunched 80–87°F market bins include the precise timing of morning marine-layer clearing, afternoon wind speeds (typically 10–15 mph from the southwest), and the strength of the thermal gradient between the coast and interior valleys. Ensemble spreads in short-range guidance reflect modest uncertainty around these factors, producing the even trader distribution across the central bins while assigning negligible probability to extremes outside 80–91°F.
