Official observations from National Weather Service stations, including Central Park, recorded a daily maximum of 90–91°F on August 9, confirming trader consensus at 100% implied probability for that bin. Warm advection ahead of a weak frontal boundary, minimal cloud cover, and light winds promoted strong daytime heating that pushed readings 6–8°F above the long-term August average of roughly 83°F. Ensemble model guidance and NWS point forecasts had converged on a peak near 91°F in the preceding days, with sea-breeze effects at coastal sites like LaGuardia adding only modest uncertainty. A late official revision or resolution tied to a secondary station could theoretically shift the exact bin, though such adjustments remain rare after preliminary data release.

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 9 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.
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 observations from National Weather Service stations, including Central Park, recorded a daily maximum of 90–91°F on August 9, confirming trader consensus at 100% implied probability for that bin.
