Official observations from Miami weather stations on September 16 confirmed a daily high of 90–91°F, aligning with National Weather Service data and driving the market’s near-certain consensus on that bin. Persistent high pressure, light winds, and above-average sea-surface temperatures along the southeast Florida coast supported daytime heating consistent with late-summer climatology, while model guidance issued in the preceding 48 hours showed tight agreement on peak readings. Resolution hinges on verified station maxima rather than forecasts, leaving minimal room for revision unless post-event quality-control adjustments alter the official record.

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 16 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 observations from Miami weather stations on September 16 confirmed a daily high of 90–91°F, aligning with National Weather Service data and driving the market’s near-certain consensus on that bin.
