Latest forecasts from AEMET and international models such as ECMWF show Madrid temperatures peaking near 38–40°C on June 23–24 amid a strong high-pressure ridge, then moderating sharply on June 25 as Atlantic air and a gentle southwesterly flow arrive. This pattern shift supports a most likely daily maximum of 31–33°C, aligning with the market’s tight clustering around those bins. Ensemble spreads remain modest because the synoptic evolution is now within the 48-hour window where high-resolution runs converge, though small timing differences in the frontal passage could still shift the peak by 1°C. Official guidance currently centers on 31–32°C, with limited upside risk from delayed cooling or localized urban heating.
