Recent National Weather Service and ensemble model guidance highlights a strengthening marine layer and onshore flow moderating maximum temperatures across coastal Los Angeles on September 1, keeping readings near or slightly above seasonal normals of 76–77°F rather than allowing full inland heating. Short-range forecasts show sunny conditions with highs clustering in the upper 70s to low 80s depending on exact location and timing of sea breezes, while longer-range outlooks note near-normal temperatures for Southern California amid a transitional pattern. With 76–77°F and 78–79°F bins nearly tied at 43% and 42.5% implied probability, traders are pricing in modest uncertainty from model spread on boundary-layer moisture and wind shifts, ahead of final NWS updates and real-time observations that will resolve the daily maximum.

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 1 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.
To toggle between Fahrenheit and Celsius, click the "Switch to US Units w/ kts" button until the relevant table displays °F.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.
