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 13 May '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.Official AEMET observations at Adolfo Suárez Madrid-Barajas Airport—the market's resolution station—confirm a daily maximum temperature of 21.5°C recorded at 18:10 local time on May 13, 2026, driving trader consensus to 100% implied probability on the 21°C outcome as evening cooling sets in under persistent cloud cover. This aligns with recent ECMWF and AEMET forecast updates anticipating capped highs of 20–22°C amid a lingering frontal system suppressing solar heating, cooler than May climatological averages near 23°C. With the update timestamped at 22:22 past peak diurnal warming (typically 16:00–19:00), realistic challenges would require a data revision uncovering an overlooked higher reading, though such adjustments are rare post-verification. Final daily RETAM summaries expected shortly will solidify resolution.
