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 4 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.
Latest National Weather Service forecasts for New York City on September 4 point to a daytime maximum in the low to mid-80s, driven by northwest winds behind a frontal passage, partial sun, and only a slight afternoon shower chance that limits strong warming. This setup aligns with the market's tight clustering around 84-85°F and 86-87°F outcomes, as ensemble guidance shows modest spread in cloud cover and boundary-layer mixing. With seasonal norms near 80°F and no strong southerly flow or ridging to boost readings higher, traders weigh the potential for brief clearing to edge the peak upward versus lingering moisture capping it lower. Updated model runs and morning observations from Central Park will provide the final resolution inputs.
