Trader consensus on Polymarket tilts toward 82-83°F (35.5%) as Miami's highest temperature on March 27, narrowly ahead of 80-81°F (27.5%), driven by the latest National Weather Service forecast guidance showing a high-pressure ridge axis over Florida fostering warm southerly flow and daytime highs in the low 80s. Ensemble model spreads from GFS and ECMWF highlight differentiating factors: core runs peak at 83°F under sunny skies and sea-breeze moderation, while cooler outliers incorporate a peripheral weak cold front potentially increasing cloudiness and northerly shear to limit peaks near 81°F. Recent 12Z updates reflect observed upper-air cooling aloft, trimming prior hotter biases; uncertainty persists ahead of 00Z runs and any diurnally driven boundary evolution, with official KMIA observations resolving the market.

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.
