Forecasts from the National Weather Service and major models indicate a high temperature in the upper 60s to low 70s for New York City on September 21, with most guidance centering near 70°F under partly sunny skies and northerly winds. This cooler-than-average reading—well below the 74°F climatological normal—reflects a post-frontal air mass with limited daytime heating and persistent cloud cover. Trader consensus heavily favors the 70-71°F bin as the most likely outcome, with 72-73°F as a secondary possibility if clearing allows slightly more insolation. The 68-69°F range captures downside risk from thicker clouds or earlier rain. Updated model runs and afternoon observations will refine the exact maximum before resolution.

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 21 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.Forecasts from the National Weather Service and major models indicate a high temperature in the upper 60s to low 70s for New York City on September 21, with most guidance centering near 70°F under partly sunny skies and northerly winds.
