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 1 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 AEMET numerical model forecasts point to a maximum temperature of 21°C in Madrid on April 1 under clear skies with northeast to north winds at 10-30 km/h, promoting diurnal heating on the high plateau, yet closely matched trader consensus favors 19°C (36%) over 20°C (30.5%) due to ensemble spread in ECMWF and GFS guidance showing variability in afternoon cloud development and wind shear. Differentiating factors include potential low-level moisture advection capping peaks at 19°C versus sustained subsidence allowing 20°C, amid Madrid's continental climate where early April climatological highs average 17°C but 2026 spring trends run warmer. Official updates from AEMET twice daily will refine probabilities ahead of resolution at Retiro or Barajas stations.
