Official observations from the National Weather Service confirmed a daily maximum of 90–91°F at Miami International Airport on September 6, aligning precisely with the market's dominant outcome. This reading occurred amid typical late-summer conditions, with afternoon sea-breeze influences and modest humidity limiting further warming beyond seasonal averages near 90°F. Prior model guidance from NOAA had converged on highs in this narrow range, and the absence of strong synoptic forcing or atypical Gulf moisture kept temperatures from exceeding the bin. Traders' near-certain positioning reflects the final verified data release, though resolution criteria tied to a single station or potential post-event adjustments remain the primary variables that could shift settlement if reexamined.

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.
