Recent numerical weather prediction models indicate a likely daily maximum temperature near 23–24°C for Madrid on May 18, supported by a stable high-pressure ridge over the Iberian Peninsula and moderate northerly flow limiting daytime heating. This aligns with mid-May climatological norms, where historical averages hover around 23°C. Minor spread in ensemble runs from the European Centre for Medium-Range Weather Forecasts and Global Forecast System accounts for the closely matched probabilities between the 23°C and 25°C outcomes, with no major synoptic disturbances forecast in the next 48 hours. Updated model cycles later today will clarify whether subtle shifts in cloud cover or wind patterns nudge the consensus higher or lower.
