Official meteorological observations from primary New York City stations, including LaGuardia Airport (KLGA) and Central Park, recorded an overnight minimum of 72–73°F on August 18, 2026, consistent with National Weather Service analyses and multiple forecast models. This outcome aligned with typical late-summer conditions featuring elevated dew points in the low 70s, light winds, and a stable air mass that limited nocturnal cooling below that threshold. Market consensus at 100% reflects verified post-event data releases rather than speculation. Only an official revision to station records or a change in the resolution source could alter the result, though such adjustments remain rare once preliminary values are confirmed.

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 18 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.
