Recent National Weather Service and ensemble model guidance points to moderating conditions over the Northeast following the mid-July heatwave, with NYC maximum temperatures on July 22 most likely falling in the 83–87°F range. Forecasters cite a shift toward southwest flow with partial cloud cover and possible afternoon seabreeze influence that caps peak heating, consistent with climatological July highs near 83°F at Central Park. Uncertainty remains around exact boundary-layer moisture and any late-day convection, which could trim or boost readings by 2–3°F depending on timing. This scientific spread underpins the tight market clustering around 84–87°F bins while limiting odds for extremes above 90°F or below 80°F. Updated NWS and GFS/ECMWF runs tomorrow morning will further refine the outlook ahead of market resolution.

This market will resolve to the temperature range that contains the highest temperature recorded at the LaGuardia Airport Station in degrees Fahrenheit on 22 Jul '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.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.Recent National Weather Service and ensemble model guidance points to moderating conditions over the Northeast following the mid-July heatwave, with NYC maximum temperatures on July 22 most likely falling in the 83–87°F range. Forecasters cite a shift toward southwest flow with partial cloud cover and possible afternoon seabreeze influence that caps peak heating, consistent with climatological July highs near 83°F at Central Park. Uncertainty remains around exact boundary-layer moisture and any late-day convection, which could trim or boost readings by 2–3°F depending on timing. This scientific spread underpins the tight market clustering around 84–87°F bins while limiting odds for extremes above 90°F or below 80°F.
