Traders see 38–39°C as the most likely range for Madrid’s highest temperature on August 18 because medium-range ensemble forecasts from the European Centre for Medium-Range Weather Forecasts and AEMET indicate a ridge of high pressure promoting clear skies and subsidence warming, with daytime maxima projected near 38°C. Historical August climatology shows Madrid’s mean daily maximum around 33–35°C, yet recent model runs highlight the potential for 1–2°C above-normal anomalies under the current pattern. Urban heat-island effects and low soil moisture from the ongoing summer further support elevated readings. Forecast uncertainty remains due to possible afternoon convection or slight shifts in the subtropical ridge, keeping 37°C and 40°C outcomes in play but at lower implied probabilities.
