Recent National Weather Service and model consensus forecasts for Los Angeles on September 26 point to overnight lows near 69–71°F, driven by a persistent marine layer with low clouds and fog that limits radiational cooling under light winds. This setup aligns with the market’s heavy weighting toward the 68–69°F bin, as coastal stations like LAX typically record minimums in that range when the stratus deck remains intact through dawn. Warmer-than-average sea surface temperatures this season have supported slightly elevated baseline lows compared to the long-term September average of 62°F, while the absence of strong offshore flow or clear-sky conditions reduces the chance of sharper drops into the mid-60s. Updated model runs and NHC-adjacent guidance issued in the past 24 hours have reinforced this narrow temperature envelope ahead of the overnight period.
