Trader consensus on Polymarket tilts toward a high of 82-83°F in Miami on March 23, driven by ensemble weather model outputs from NOAA's GFS and ECMWF, which cluster around 82-84°F amid building high pressure and moderating trade winds. This edges out 80-81°F (22.5% implied odds) due to above-normal sea surface temperatures boosting daytime heating, while 84-85°F (20.5%) gains from potential delayed sea breeze onshore flow allowing prolonged solar insolation. Differentiating factors include model spread from transient cloud cover risks and urban heat island amplification at MIA airport observation site; historical March 23 highs average 80°F but vary ±4°F with wind shear. Upcoming 00z model runs could shift odds as diurnal boundary layer evolution refines peak temperature projections.

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.
