Official observations at Adolfo Suárez Madrid–Barajas Airport, the market's resolution source via Weather Underground, recorded a maximum temperature of 13°C on March 29, 2026, yielding 100% trader consensus on this outcome as positions settled post-event. Supporting AEMET data from the station logged a nearby peak of 14.4°C at 16:50 amid overcast skies, light northerly winds, and high humidity that limited solar heating and kept readings below late-March climatological averages of 16–17°C. This cool anomaly reflects a stable high-pressure ridge to the north funneling chilly air southward. With data now finalized, realistic challenges are limited to rare source revisions or measurement discrepancies between stations.
