Recent ensemble forecasts from major weather models position 37–38°C as the most probable range for Madrid’s June 20 high, driven by a strong subtropical ridge delivering clear skies, light northerly winds, and efficient daytime heating across the central Meseta. Current conditions show Madrid already running several degrees above seasonal normals, with the approach of the summer solstice further boosting insolation. Latest model runs indicate limited cloud development and negligible precipitation risk, keeping maximum temperatures firmly in the upper 30s while capping the chance of reaching 40°C or higher. Traders have responded by concentrating probability on 37–38°C, reflecting the narrow but well-supported forecast spread ahead of final verification on the 20th.
