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 15 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 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 highest temperature of 24°C (43.5% implied probability) in Madrid today, closely trailed by 23°C (28%) and 25°C (22%), reflecting ensemble guidance from ECMWF and GFS models projecting peak daytime heating to 23-25°C under a persistent high-pressure ridge over Iberia. AEMET's official forecast specifies a 23°C maximum with minimums near 8-10°C, light northerly winds at 15 km/h, and clear skies (0% precipitation risk), consistent with morning observations at Barajas Airport showing lows around 8°C and steady diurnal warming. April climatology averages 18°C highs, but recent sunny days have elevated baselines; minor uncertainties in afternoon cloud cover or sea-breeze effects could tip the exact integer degree, with intraday AEMET updates and 12Z model runs pivotal before resolution on verified station data.
