Current forecasts from the National Weather Service and other models indicate a high near 78–81°F (26–27°C) for Los Angeles on September 18, supported by clear skies, light to moderate southwest winds, and limited marine layer intrusion under moderate high pressure. Trader sentiment clusters tightly around 74–79°F because small differences in onshore flow strength, exact clearing timing, or afternoon wind shifts can alter peak readings by a few degrees at official stations. These conditions align closely with the long-term September average high of about 76°F at Los Angeles International Airport, with recent El Niño-driven ocean warmth having less influence this late in the season. Updated NWS model runs and afternoon observations will refine the final 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 18 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 forecasts from the National Weather Service and other models indicate a high near 78–81°F (26–27°C) for Los Angeles on September 18, supported by clear skies, light to moderate southwest winds, and limited marine layer intrusion under moderate high pressure.
