Recent National Weather Service forecasts and model consensus for Miami on September 5 point to a daily minimum in the upper 70s to low 80s amid persistent southeast flow, high moisture content, and scattered afternoon thunderstorms that limit overnight radiative cooling. These conditions align with climatological norms for early September, where average lows hover near 77°F but often run a few degrees warmer under similar humid, disturbed patterns with mid-level ridging. Trader emphasis on the 80-81°F and 78-79°F ranges reflects the latest guidance showing minimal deviation from this baseline, while lower or much higher outcomes remain less favored absent a stronger frontal passage or unexpected clear-sky cooling. Updated model runs and NHC-adjacent discussions through the weekend will refine overnight lows ahead of 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.
