Official observations from Milan meteorological stations, including data aggregated by ilMeteo.it and aligned with Milan Linate Airport readings, confirm the highest temperature on April 21, 2026, reached 19°C, driving trader consensus to a 100% implied probability for this outcome. Partly cloudy skies and moderate easterly winds capped daytime heating despite a warmer-than-average April anomaly of +2°C above historical norms, matching pre-event numerical weather prediction model consensus from ECMWF and GFS ensembles projecting peaks near 19°C. With the event passed and data finalized, realistic challenges are limited to rare official revisions by the resolving authority, such as the Italian Aeronautica Militare service.
