Recent National Weather Service forecasts highlight a warming trend across the Los Angeles basin ahead of September 9, driven by strengthening high pressure and reduced marine layer influence, with downtown and valley areas projected to reach the mid-90s while coastal stations like LAX remain in the upper 80s. Official model consensus points to highs near 89–98 °F depending on exact location and timing of any sea breeze, creating tight clustering in market-implied odds around the 86–91 °F range. Historical September averages near 76–77 °F underscore the anomalous warmth, yet typical late-summer variability from onshore flow introduces uncertainty in final daily maxima. Updated NWS guidance and ensemble runs over the next 48 hours will likely refine these projections before resolution.

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 9 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.Recent National Weather Service forecasts highlight a warming trend across the Los Angeles basin ahead of September 9, driven by strengthening high pressure and reduced marine layer influence, with downtown and valley areas projected to reach the mid-90s while coastal stations like LAX remain in the upper 80s.
