Strong model consensus and real-time observations from Spanish meteorological agencies support the market's 100% implied probability for a 35°C high in Madrid on June 17, with afternoon readings climbing under clear skies, light easterly winds, and minimal cloud cover that maximizes solar heating. June climatology places typical maxima near 28–30°C, yet persistent high-pressure systems and above-average soil dryness have amplified daytime warming this week, aligning forecasts from multiple runs at or above the threshold. Late-day cooling or minor measurement variations at official stations could still shift the final recorded peak by 1–2°C, though current conditions make such deviations unlikely before sunset.
