Current numerical weather prediction models from sources including the European Centre for Medium-Range Weather Forecasts show a stable high-pressure pattern over central Spain, supporting maximum temperatures of 35–36 °C in Madrid on August 19, which aligns with the market’s leading 36 °C (36.5 %) and 35 °C (24.5 %) outcomes. These values sit slightly above the long-term August average high of 32–34 °C but remain below extreme heatwave thresholds. Recent model runs have shown minimal day-to-day shifts, reducing uncertainty around intensification or cooling from Atlantic flow. Traders are also pricing in the possibility of 37 °C (19.5 %) if afternoon insolation strengthens under clear skies, while lower or higher extremes carry low implied probability given the current consensus and proximity to the observation date.
