**Northeast winds and post-frontal cooling have locked in a highest temperature for New York City on September 22, 2026, within the 68–69 °F band.** Official National Weather Service forecasts and short-range model guidance, including runs from the GFS, consistently project an afternoon high in the upper 60s under mostly cloudy skies, with LaGuardia Airport observations aligning near this range as of late afternoon. Historical analogs for late-September cold-front passages support highs of 63–69 °F, and the current synoptic pattern—persistent northeast flow with dew points in the low-to-mid 50s—has kept temperatures from exceeding this narrow window. The market’s 99.9 % implied probability on 68–69 °F reflects this strong model consensus and real-time surface data. Only an unexpected late-day surge above 70 °F or a sharp downward revision in verified observations could shift resolution outside this band.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the LaGuardia Airport Station in degrees Fahrenheit on 22 Sep '26.
The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=klga
This market will resolve off of the Hourly Data provided using the "Show Hourly Data" button.
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to US Units w/ kts" button until the relevant table displays °F.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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.**Northeast winds and post-frontal cooling have locked in a highest temperature for New York City on September 22, 2026, within the 68–69 °F band.** Official National Weather Service forecasts and short-range model guidance, including runs from the GFS, consistently project an afternoon high in the upper 60s under mostly cloudy skies, with LaGuardia Airport observations aligning near this range as of late afternoon.
