This market will resolve to the temperature range that contains the highest temperature recorded at the LaGuardia Airport Station in degrees Fahrenheit on 21 Apr '26. The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the LaGuardia Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/us/ny/new-york-city/KLGA. To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C. This market can not resolve to "Yes" until all data for this date has been finalized. 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. Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.Official National Weather Service observations at Central Park, New York City's primary climate station, recorded a maximum temperature of 53°F at 2:57 PM EDT on April 21, 2026, driving Polymarket traders to assign 100% implied probability to the 52-53°F outcome based on Weather Underground data from LaGuardia Airport (KLGA), the market's resolution source. This positioning reflects verified hourly METAR reports amid cloudy skies, light winds, and lingering effects from a cold front that followed mid-April's record 90°F heat in Central Park on the 15th—well below the 64°F climatological average high. With data finalized in NWS daily climate summaries, only an extraordinary station measurement revision, as occasionally seen in quality control audits, could realistically challenge this consensus.
