Recent official forecasts from the National Weather Service and models place Miami's August 31 high near 88–90°F amid typical late-summer humidity, easterly flow, and a 60–70% chance of afternoon thunderstorms. These conditions often limit peak readings through cloud cover and evaporative cooling, supporting the market's heavy weighting on the 90–91°F and 92–93°F bins. Sea-breeze convergence and moisture from the Gulf Stream further stabilize temperatures in the low 90s, consistent with climatological averages near 90°F. Updated model runs showing slightly drier mornings could allow brief spikes toward 92–93°F, while heavier rain timing remains the key uncertainty for traders monitoring final NHC and local office briefings.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Miami Intl Airport Station in degrees Fahrenheit on 31 Aug '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=kmia
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.
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.Recent official forecasts from the National Weather Service and models place Miami's August 31 high near 88–90°F amid typical late-summer humidity, easterly flow, and a 60–70% chance of afternoon thunderstorms.
