Recent forecast models from the European Centre for Medium-Range Weather Forecasts and Spain’s AEMET indicate Madrid’s daytime high on May 22 will likely peak at 32–33 °C, driven by a persistent ridge of high pressure that favors clear skies, strong solar heating, and minimal cloud cover or wind mixing. This setup, occurring amid above-average May conditions where typical highs reach only 24–26 °C, has concentrated trader consensus on the 33 °C outcome at 42.5 % implied probability, followed by 32 °C at 28 %. Light southerly winds and dry air further support modest warming without triggering convective cooling. The next AEMET and ECMWF model runs, expected within the next 12–24 hours, will determine whether any subtle ridge adjustments push the peak toward 34 °C or hold it near 32 °C.
