Official National Weather Service observations confirm Miami’s overnight low reached 74–75°F on May 16, driving the near-certain market-implied odds. This outcome reflects persistent warm, humid air advection from the Gulf Stream under light southerly flow, which limited nocturnal radiative cooling despite clear skies. Late-spring climatology for the region typically produces minimums between 72–77°F, and the absence of any frontal passage or unusual subsidence kept temperatures within the narrow historical envelope. Final certified readings from Miami International Airport are expected to lock in resolution without meaningful adjustment.

This market will resolve to the temperature range that contains the lowest temperature recorded at the Miami Intl Airport Station in degrees Fahrenheit on 16 May '26.
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.
