This market will resolve to the temperature range that contains the highest temperature recorded at the Miami Intl Airport Station in degrees Fahrenheit on 18 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.Trader consensus on Polymarket prices 84-85°F as the leading outcome at 43.5% implied probability for Miami's highest temperature on April 18, driven by National Weather Service climatological normals of 84°F for mid-April and recent forecast model ensembles converging on mid-80s peaks. A persistent upper-level high-pressure ridge has promoted subsidence and mostly sunny skies, with easterly winds of 10-15 mph advecting continental air masses while limiting sea breeze incursions that could otherwise cool interiors. Recent observations at Miami International Airport show highs reaching 87°F earlier this week, above the 82-83°F monthly average, but models indicate slight moderation due to increasing marine influence. Key uncertainties include isolated showers or stronger onshore flow; watch NWS Miami's afternoon updates for refined guidance ahead of resolution based on official KMIA measurements.
