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 12 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 observations from the National Weather Service at Los Angeles International Airport recorded a daily maximum of 81°F on September 12, 2026, under mostly sunny conditions with light onshore flow and a moderating marine layer typical for the coastal basin in mid-September. This outcome aligns with the seasonal average high near 76°F and recent cooling after an early-month heat spike that reached 99°F on September 9. Trader consensus at near-100% probability for the 80-81°F bin reflects verified station data and minimal model divergence in post-event verification. Resolution could shift only if official climatological summaries revise the peak reading due to station-specific calibration or if the market specifies a non-standard observation site outside the primary NOAA network.
