Highest temperature in Madrid on July 25?

Platform comparison

Market context

Madrid's summer heat peaks in late July, with the city regularly experiencing temperatures exceeding 35°C during this period. The Adolfo Suárez Madrid-Barajas Airport station, situated on the city's northern periphery, typically records slightly lower maxima than central Madrid due to its elevation and distance from urban heat islands, though it remains subject to the same continental high-pressure systems that dominate the Iberian peninsula in midsummer. Historical data from the airport station shows that temperatures on 25 July have ranged from 28°C to 38°C over the past two decades, with the most common outcomes clustering between 33°C and 36°C.

The 3% implied probability assigned to this market likely reflects the specificity of the resolution criteria rather than genuine uncertainty about whether Madrid will be warm on that date. Traders should monitor European weather forecasting models from mid-July onwards, particularly the ECMWF and GFS systems, which typically provide reliable guidance five to ten days ahead. Anomalous heat waves driven by Saharan air masses or blocking high-pressure systems could push temperatures into the upper 38°C range, though such extremes remain statistically uncommon for this particular location and date. The settlement window closes at midday, capturing only morning and early afternoon readings, which may exclude the absolute daily maximum typically occurring in late afternoon.
