**Forecasts from the National Weather Service and private models show NYC highs clustering in the upper 70s on August 21, 2026, with official guidance pointing to around 77–80°F under partly sunny skies and northeast winds of 5–10 mph.** Recent observations from Central Park and nearby airports indicate cooling after warmer prior days, driven by a post-frontal air mass with lower dew points and reduced insolation from morning cloud cover. Light shower chances (around 20%) could further cap peak heating by limiting surface warming and enhancing evaporative cooling. The near-even split between the 78–79°F (34.5%) and 80–81°F (34.0%) outcomes reflects genuine uncertainty in the precise maximum: small differences in afternoon cloud breaks, wind gusts, or urban heat island effects at the official observation site can shift the daily high across that threshold. Historical August 21 normals near 83°F provide context, but the current synoptic setup favors values below that baseline. Updated model runs and hourly observations through midday will likely resolve the narrow gap.

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 21 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.**Forecasts from the National Weather Service and private models show NYC highs clustering in the upper 70s on August 21, 2026, with official guidance pointing to around 77–80°F under partly sunny skies and northeast winds of 5–10 mph.**
