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 4 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.Latest ECMWF and GFS ensemble forecasts cluster Madrid's highest temperature on April 4 around 22-24°C amid a mild high-pressure ridge building over Iberia, fostering subsidence and clear skies that suppress clouds and boost daytime heating, explaining trader-implied probabilities favoring 23°C (34.5%) slightly over 24°C (28%). AEMET's municipal outlook projects a warmer 25°C peak with light northerly winds and zero precipitation risk, but ensemble spreads highlight uncertainty from ridge positioning and boundary-layer mixing variations. This setup exceeds the climatological April 4 average of 18°C amid a warmer-than-normal spring 2026 anomaly; new model runs and AEMET updates through April 3 could refine the closely matched outcomes.
