Traders have converged on 38°C as the implied outcome for Madrid’s highest temperature on July 31, 2026, reflecting the latest official forecasts from Spain’s AEMET and supporting European models that project a daytime maximum near this threshold under stable high-pressure conditions. Historical July averages hover around 32–33°C, but persistent heatwave patterns and minimal cloud cover have elevated expectations, with current observations and model runs showing limited variability in peak readings at representative urban stations. This near-certainty stems from consistent numerical guidance and real-time data, though minor deviations remain possible if localized wind shifts or measurement timing at the primary station alter the recorded high by 1°C.
