This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the LaGuardia Airport Station in degrees Fahrenheit on 8 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=klga 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 forecasts and ensemble model consensus position the highest temperature in New York City on September 8 around 82–83°F. As of September 7, NWS products for Central Park and LaGuardia show projected daytime maxima of 82–84°F under mostly sunny to partly cloudy skies, light northwest winds, and negligible precipitation chances. This places the outcome slightly above the long-term September 8 average high near 79°F. Trader-implied probabilities heavily favor the 80–83°F bin (87.5% combined) because current atmospheric conditions—stable high pressure and minimal moisture—support modest warming without significant deviation. The resolution hinges on the official Central Park observation, with final model runs and any late-day adjustments representing the primary remaining uncertainty before the market settles.
