Recent National Weather Service and model guidance indicate New York City will see an overnight low near 65°F on August 21, 2026, driving trader consensus toward the 66-67°F and 64-65°F bins. Mild maritime air, light winds, and partial cloud cover are limiting radiational cooling, while dew points in the upper 50s to low 60s support this range. August climatology places the average daily minimum at 67°F, and current forecasts align closely with that baseline rather than any sharp departure. Updated model runs through the evening will refine the exact minimum recorded at Central Park or LaGuardia before resolution.

This market will resolve based on the lowest 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 lowest temperature recorded at the LaGuardia Airport Station in degrees Fahrenheit on 21 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the lowest 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.
