Recent forecasts from Spain’s AEMET alongside BBC Weather and eltiempo.es indicate a daytime maximum of 36–38 °C for Madrid on 17 August under stable anticyclonic conditions, light northeasterly flow, and clear skies that promote intense surface heating. This aligns with an ongoing above-normal temperature anomaly across central Iberia, where mid-August readings have frequently reached 37–40 °C. Numerical model consensus shows negligible cloud cover or precipitation that could moderate peaks, while Madrid’s continental setting and urban heat-island effect reinforce values near the upper end of late-summer climatology. Trader consensus has therefore concentrated implied probability on 37 °C at 51.5 %, with 36 °C and 38 °C as the next most likely outcomes 24 hours before resolution.
