Latest National Weather Service forecasts and ensemble guidance from GFS and ECMWF models project Miami's lowest temperature on May 16 around 76-79°F, reflecting trader consensus with 32% implied probability for 76-77°F and 30% for 78-79°F. This clustering stems from persistent southerly flow and high boundary layer moisture limiting radiational cooling overnight, alongside warm sea surface temperatures near 82°F off South Florida's coast. Differentiating factors include potential evening cloud cover variations and light winds, which could enhance cooling for the lower bin or trap heat for the higher; historical May climatology averages 74°F lows, but current patterns favor warmer outcomes. Monitor 12Z model runs today and NWS updates for refinements ahead of 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.
