Official National Weather Service forecasts for Miami on September 10 project a daytime high near 89°F under partly sunny skies with a 60-70% chance of afternoon showers and thunderstorms. This consensus, reflected in the close market-implied odds between the 88-89°F and 90-91°F bins, stems from typical late-summer steering patterns with easterly flow and abundant tropical moisture that favor scattered convection by midday or early afternoon. Such storms often suppress peak temperatures by increasing cloud cover and evaporative cooling before the daily maximum is reached. Model runs show limited spread in timing of initiation, with historical September climatology supporting highs of 89-90°F as the most probable range absent a drier airmass or delayed sea-breeze trigger. Updated NHC and local office guidance through the next 48 hours will refine whether earlier or more widespread activity tilts resolution toward the lower bin.

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 10 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.Official National Weather Service forecasts for Miami on September 10 project a daytime high near 89°F under partly sunny skies with a 60-70% chance of afternoon showers and thunderstorms.
