Trader consensus heavily favors 74-75°F (43.5%) over 76-77°F (34.5%) for Miami's March 19 high temperature, reflecting NOAA's National Weather Service forecast of 74-77°F amid a lingering weak cold front and sea breeze onshore flow that caps peaks below the mid-70s. Differentiating factors include model ensemble spreads—ECMWF leaning cooler at 74°F due to increased low-level clouds, while GFS hints at 76°F with partial clearing—historical March averages of 78°F, and station-specific measurements at Miami International Airport, where afternoon convection often shaves 1-2°F off modeled highs. Upcoming 12Z model updates could shift odds if ridging strengthens, underscoring typical 2-3°F forecast uncertainty at 48 hours out.

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.
