Recent National Weather Service and model consensus point to a moderating marine layer and southwest flow aloft returning after a late-August heat wave, positioning the highest temperature in Los Angeles on August 31 near 80–85 °F. Onshore winds and increased low-cloud coverage are expected to cap daytime heating below the 87–91 °F readings seen August 27–30, aligning closely with the 78–79 °F and 80–81 °F bins that dominate market-implied odds. Historical climatology shows a 76.8 °F average high for the date, while current ensemble guidance and the absence of offshore winds or clear-sky amplification keep probabilities for 82 °F or higher low. Traders are weighting the stable, short-range forecast window heavily, with any last-minute model shift in marine-layer depth or wind direction as the primary remaining uncertainty before resolution.
