Latest National Weather Service forecasts and NOAA model ensembles project Miami's highest temperature on March 27 at 82-83°F, reflecting trader-implied probabilities of 33.5% for that bin amid close competition with 80-81°F at 27.5%, underscoring uncertainty in sea breeze timing and afternoon cloud cover. Ensemble guidance from GFS and European models shows a tight spread around 81-83°F, influenced by persistent high pressure over Florida suppressing cooler air intrusions following a weak frontal passage earlier in the week. Historical late-March averages hover near 80°F, but above-normal sea surface temperatures in the Atlantic support slight warm biases. Diurnal fluctuations and urban heat island effects could differentiate outcomes; real-time observations from MIA airport will resolve by evening.

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.
