Recent ensemble forecasts from the European Centre for Medium-Range Weather Forecasts and Global Forecast System show a daily maximum temperature in Madrid on May 18 most likely between 23°C and 25°C, aligning with the market's strongest implied probabilities at those levels. These models incorporate current atmospheric conditions, including stable high-pressure systems and typical springtime warming patterns over the Iberian Peninsula, which historically support highs near seasonal averages of 22–24°C. Traders appear to weigh the narrow spread in model outputs and limited variability from recent observations, though minor shifts in wind patterns or cloud cover could adjust final readings at the Adolfo Suárez Madrid-Barajas Airport station. Updated model runs expected overnight will provide the next key data point for resolution.
