Persistent marine layer influence and typical August climatology for coastal Los Angeles are anchoring trader sentiment around a 66–69°F minimum, consistent with NWS guidance showing overnight lows near 68°F at KLAX amid dew points of 62–66°F and light onshore flow. Daytime highs reaching the mid-80s to low-90s under clear to partly cloudy skies allow modest radiational cooling overnight, but elevated humidity and the urban heat island limit drops below the historical 66°F August average. Recent model runs and observations indicate no significant onshore push or marine stratus deepening that would push the low into the low- to mid-60s, while the absence of strong offshore winds precludes warmer readings above 70°F. Updated NHC and local forecast discussions through the evening will refine the exact threshold as the diurnal minimum approaches.
