This market will resolve to the temperature range that contains the highest temperature recorded at the Miami Intl Airport Station in degrees Fahrenheit on 19 May '26. 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.Recent National Weather Service and AccuWeather model guidance points to a daily high in Miami on May 19 between 84°F and 89°F, driven by typical late-spring subtropical conditions with sea-surface temperatures near 80°F and light easterly flow limiting rapid warming. The tight market split between 86-87°F and 88-89°F reflects modest uncertainty in afternoon cloud cover and boundary-layer moisture, which can suppress or enhance peak readings by 1–2°F. Historical May averages hover near 85°F, with occasional excursions above 88°F when ridging strengthens; traders are therefore weighting the most recent ensemble runs showing limited daytime heating against the small but real chance of clearer skies. Updated forecast discussions expected late today could shift implied probabilities if dew-point trends or wind forecasts change.
