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 25 Aug '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. To toggle between Fahrenheit and Celsius, click the "Switch to US Units w/ kts" button until the relevant table displays °F. This market can not resolve until the first data point for the following date has been published on the resolution source. 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.
Forecast models from the National Weather Service and private sources converge on mostly sunny skies with west-northwest winds of 5-10 mph for New York City on August 25, supporting surface heating under high pressure. This setup favors a daily maximum in the upper 70s to low 80s, with the precise peak hinging on afternoon convective development that could shave 1-2°F through cloud cover or brief showers. Urban heat island effects at Central Park and slight model spread in boundary-layer moisture create the narrow gap between 78-79°F and 80-81°F bins, while climatological August norms near 83°F underscore why traders assign low probability to 82°F-plus outcomes. Updated model runs overnight will refine these thresholds ahead of market resolution.
