This market will resolve to the temperature range that contains the highest temperature recorded at the Adolfo Suárez Madrid-Barajas Airport Station in degrees Celsius on 27 Mar '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 Adolfo Suárez Madrid-Barajas Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/es/madrid/LEMD. 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 Celsius (eg, 9°C). 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 heavily favors a high temperature of 18°C in Madrid on March 27 at 95.3% implied probability, driven by the latest forecasts from Spain's official meteorological agency, AEMET, which project a daytime maximum of 18°C under persistent high-pressure conditions and clear skies. Ensemble model runs from ECMWF and GFS align closely on this outcome, reflecting stable atmospheric patterns with mild southerly flows limiting further warming after recent cool snaps. Historical March norms for Madrid average 15–16°C, making 18°C plausible but not extreme. Realistic challenges include unexpected cloud cover or a sudden frontal shift, though low-probability per current guidance; hourly updates from AEMET through the day will refine this as observations near.
