**Latest National Weather Service and private forecast models indicate a peak temperature near 88–90°F for Miami on September 4, aligning with the near-even market split between the 88–89°F (41.5%) and 90–91°F (37.0%) bins.** Typical late-summer conditions—southeast winds of 5–10 mph, high boundary-layer moisture, and scattered to likely afternoon thunderstorms—create modest uncertainty in the exact maximum. Thunderstorm timing and coverage can either cap heating through cloud cover and evaporative cooling or allow brief sun breaks to push readings slightly higher. Historical climatology shows an average September 4 high of roughly 90°F at Miami International Airport, providing context for current guidance. Updated model runs and the morning NWS forecast discussion will likely narrow the range before resolution.

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 4 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=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.
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.**Latest National Weather Service and private forecast models indicate a peak temperature near 88–90°F for Miami on September 4, aligning with the near-even market split between the 88–89°F (41.5%) and 90–91°F (37.0%) bins.** Typical late-summer conditions—southeast winds of 5–10 mph, high boundary-layer moisture, and scattered to likely afternoon thunderstorms—create modest uncertainty in the exact maximum.
