Official National Weather Service observations from Los Angeles International Airport recorded a maximum of 81°F on September 5, 2026, aligning precisely with the 80-81°F bin that now holds full market-implied probability. This outcome reflects typical early-September marine layer influence moderating coastal highs near the 77°F seasonal normal, with light onshore flow and minimal cloud cover allowing modest warming without extreme heat. Downtown stations reached the low 90s under clearer inland conditions, but the market resolves on the primary coastal airport metric used for such contracts. Only an unexpected revision to the preliminary local climatological data or a shift in the designated reporting station could alter the result before final certification.

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 5 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.Official National Weather Service observations from Los Angeles International Airport recorded a maximum of 81°F on September 5, 2026, aligning precisely with the 80-81°F bin that now holds full market-implied probability.
