Official observations from the Adolfo Suárez Madrid-Barajas Airport weather station, managed by Spain's State Meteorological Agency (AEMET), confirm the highest temperature on May 9, 2026, peaked at 17°C around 15:00 local time, driving trader consensus to 100% on this outcome. Cloudy skies, scattered showers, and a cooler air mass associated with an unstable weather pattern suppressed daytime heating, aligning with European Centre for Medium-Range Weather Forecasts (ECMWF) model guidance from prior days. This positioning reflects verified hourly data with minimal uncertainty, as airport METAR reports and AEMET summaries show no exceedance. Realistic challenges would require rare data revisions from sensor recalibration, but final audits typically affirm preliminary records.
