Trader consensus on Polymarket assigns a 100% implied probability to 17°C as the highest temperature at Adolfo Suárez Madrid-Barajas Airport on April 2, 2026, driven by official AEMET observational data from the airport's automated station confirming a midday peak of 17°C under partly cloudy skies and cool northerly winds suppressing highs below seasonal norms of around 18°C. Hourly measurements tracked steady temperatures from morning lows near 6°C, with no spikes exceeding 17°C by day's end, aligning with pre-event forecast model consensus from AEMET predicting 17–19°C amid stable atmospheric conditions. Scenarios challenging this near-certainty include rare post hoc data revisions during AEMET quality control or discrepancies in final validated records, though such adjustments are infrequent for routine daily observations.
