Recent National Weather Service and model guidance for Miami indicates a Wednesday low in the upper 70s to low 80s, aligning with the closely matched market leaders at 78–79 °F and 80–81 °F. Persistent easterly flow, high dew points near 77–80 °F, and scattered afternoon thunderstorms limit overnight radiative cooling while maintaining elevated minimums typical of September’s climatology (historical average low near 77 °F). Model consensus shows limited spread on steering patterns and moisture, keeping the 71 °F-or-below outcome at 23.5 % amid modest uncertainty from variable cloud cover and storm timing. Updated NHC and local forecast discussions through September 8 will refine these thresholds ahead of market resolution.

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 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.
