This market will resolve to the temperature range that contains the highest temperature recorded at the Miami Intl Airport Station in degrees Fahrenheit on 17 Apr '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.Official observations from Miami International Airport (KMIA), as reported by Weather Underground and the National Weather Service, confirm the highest temperature on April 17 reached 84-85°F, driving trader consensus to near-certainty at 100% implied probability for this outcome. This aligns precisely with pre-event National Weather Service short-fuse forecasts projecting daytime peaks near 85°F under a dominant subtropical ridge fostering subsidence, light east-southeast winds around 8-10 knots, and mostly sunny skies that limited cloud cover and enhanced solar heating. April climatological normals sit at 84°F, with model ensembles like the High-Resolution Rapid Refresh showing tight agreement on these conditions amid low humidity and minimal sea-breeze disruption. Realistic challenges would require an improbable post hoc data revision from automated station logs or METARs, as multi-source validations rarely diverge.
