Recent National Weather Service and local model guidance indicate a marine layer is returning to coastal Southern California by early September, promoting overnight radiative cooling under clearer skies and lighter winds following the recent heatwave relief. Forecasts for Los Angeles on September 1 consistently point to overnight lows near 64°F, aligning closely with the 1991–2020 climatological average of 64.7°F for the date, with some guidance ranging 62–66°F depending on marine layer depth and timing. This setup favors mid-60s readings over extremes, though modest uncertainty remains in the precise minimum due to variations in onshore flow strength and urban heat island effects. The near-even market split between sub-58°F and 76°F+ outcomes reflects trader assessment of potential forecast shifts before official observations, likely from stations such as Los Angeles International Airport, resolve the market.

This market will resolve to the temperature range that contains the lowest 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 lowest 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.
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.Recent National Weather Service and local model guidance indicate a marine layer is returning to coastal Southern California by early September, promoting overnight radiative cooling under clearer skies and lighter winds following the recent heatwave relief.
