Official observations from National Weather Service stations, including Central Park, recorded a maximum of 85–87°F on August 19, 2026, under building high pressure, southerly flow, and mostly sunny skies that limited cloud cover and allowed efficient daytime heating. Ensemble model guidance and point forecasts had centered near this range days earlier, aligning trader consensus with the measured outcome and producing the 100% market weighting on the 86-87°F bin. Historical August averages near 83–84°F provide context, while realistic challenges to this resolution remain limited to post-event data revisions or station-specific discrepancies, both rare once preliminary climate summaries are issued.

This market will resolve based on the highest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section.
This market will resolve to the temperature range that contains the highest temperature recorded at the LaGuardia Airport Station in degrees Fahrenheit on 19 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the LaGuardia Airport Station, 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 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.
