Recent National Weather Service guidance and ensemble model runs from the GFS and ECMWF indicate a nocturnal low in Miami near 74–76°F on May 20, driven by moderate easterly flow off the Atlantic, dew points holding around 72°F, and potential for increased cloud cover limiting daytime heating before radiative cooling overnight. This positions the 73°F-or-below outcome as the market leader at 47.5% implied probability, consistent with mid-May climatological normals of 76–77°F at Miami International Airport but tempered by the subtropical moisture that caps strong temperature drops. Traders are weighting the 78–81°F range next at roughly 40% combined, reflecting minor model spread in wind and precipitation timing. Updated hourly forecasts through the weekend will refine these thresholds ahead of official airport observations used for resolution.

The resolution source for this market will be information from Wunderground, specifically the lowest temperature recorded for all times on this day by the Forecast for the Miami Intl Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/us/fl/miami/KMIA.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
This market can not resolve to "Yes" until all data for this date has been finalized.
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.
Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.
