Official observations from Miami International Airport recorded a minimum temperature of 77–79°F on August 26, 2026, aligning closely with the 1991–2020 climatological average low of 77.6°F for the date. Persistent subtropical high pressure, elevated dew points near 76°F, and light easterly winds limited nocturnal radiative cooling typical of late-summer nights in South Florida. With the market-implied probability for 78–79°F exceeding 99%, traders converged on the outcome supported by National Weather Service data and historical analogs showing rare departures below 76°F absent strong frontal passages. An unexpected cold surge or measurement revision could theoretically alter resolution, though none materialized.

The resolution source for this market will be information from NOAA, specifically the lowest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=kmia
This market will resolve off of the Hourly Data provided using the "Show Hourly Data" button.
If NOAA data is unavailable or missing for the observation period, Weather Underground will be used as the secondary resolution source.
To toggle between Fahrenheit and Celsius, click the "Switch to US Units w/ kts" button until the relevant table displays °F.
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.
