Trader consensus on Polymarket heavily favors 74-75°F (39.5%) and 76-77°F (36.5%) for Miami's highest temperature on March 19, driven by converging NOAA GFS and ECMWF ensemble forecasts projecting peaks of 74-77°F amid a lingering cool upper-level trough and persistent onshore breezes. These conditions suppress highs below the 78°F March 19 climatological average, with sea surface temperatures near 76°F aiding moderation. Differentiating factors include model spread on afternoon sea breeze onset—earlier penetration favors 74-75°F by enhancing low-level convergence and cloudiness, while delays tilt toward 76-77°F. Historical volatility (±3°F) and urban heat effects add uncertainty; monitor 12Z updates for refinements.

The resolution source for this market will be information from Wunderground, specifically the highest 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.
