**Official National Weather Service forecasts and supporting model consensus project a daily maximum of 79°F in New York City on September 5 under partly to mostly cloudy skies with northerly flow around 5–10 mph.** This setup, following several warmer days earlier in the week, favors a peak in the upper 70s rather than pushing into the low 80s. Real-time surface observations from Central Park and area airports have tracked closely with these guidance trends throughout the day. The dominant 78–79°F market outcome reflects traders’ alignment with this high-confidence forecast from authoritative sources, though minor deviations remain possible if unexpected breaks in cloud cover enhance insolation or if steering winds weaken more than anticipated.

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 5 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.**Official National Weather Service forecasts and supporting model consensus project a daily maximum of 79°F in New York City on September 5 under partly to mostly cloudy skies with northerly flow around 5–10 mph.** This setup, following several warmer days earlier in the week, favors a peak in the upper 70s rather than pushing into the low 80s.
