This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Los Angeles International Airport Station in degrees Fahrenheit on 4 Sep '26. The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=klax This market will resolve off of the Hourly Data provided using the "Show Hourly Data" button. If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source. In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket. To toggle between Fahrenheit and Celsius, click the "Switch to US Units w/ kts" button until the relevant table displays °F. This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first. The resolution source for this market measures temperatures to whole degrees Fahrenheit (eg, 21°F). Thus, this is the level of precision that will be used when resolving the market. Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.Current model consensus from NWS and private forecasters shows morning marine layer and onshore flow moderating Los Angeles temperatures on September 4 near the 76.7°F climatological average high, with afternoon clearing under mostly sunny skies. This setup positions the 76-77°F bin as the market leader at 37% implied probability, followed by 78-79°F at 27%, reflecting typical September conditions without strong offshore winds or thermal trough development that would push readings higher. Recent observations from Los Angeles International Airport confirm stable patterns, with September 1 reaching only 76°F and no heat signals in GFS or NAM runs through the period. Traders are weighting these factors heavily ahead of final National Weather Service verification.
