Official National Weather Service observations and forecast models for mid-August 2026 placed New York City under typical summertime high pressure with light winds, supporting a daily maximum of 86–87 °F at LaGuardia Airport. This aligned closely with climatological normals near 84 °F and recent model runs showing minimal diurnal variation or marine influence. Trader consensus at 100 % for the 86–87 °F bin reflects the narrow uncertainty range once the event day began, as surface data and regional soundings confirmed limited potential for deviation. Only an unforecasted coastal front or station-specific microclimate shift could have altered the outcome before final readings.

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 13 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.
