Highest temperature in Madrid on July 12?

Platform comparison

Market context

Madrid is currently experiencing an intense heatwave that has pushed temperatures well above seasonal averages across central Spain, with the city recording highs of 42°C earlier in July. The settlement window for this market closes at noon on 12 July 2026, capturing the peak temperature at Barajas Airport for that specific day. Despite the current crowd-implied probability of 0% for a "YES" outcome, the historical context suggests a significant deviation from typical July conditions, as the first half of 2026 has already been confirmed as Spain’s hottest ever recorded, with temperatures averaging 1.6°C above normal levels [10].

Recent comparable cases frame this probability as potentially mispriced, given that Barcelona recorded 40.5°C on 8 July, setting a new maximum since records began, while Madrid itself hit 42°C between 4–7 July [2][5]. The average high for July in Madrid is typically 35°C (95°F), but the current forecast for July 2026 shows daily highs ranging from 32°C to 39°C (89°–102°F), indicating a sustained period of extreme heat that could easily breach previous thresholds on the settlement date [1]. Traders should monitor the official Wunderground data for Barajas Airport specifically, as regional alerts have concentrated severe warnings in the metropolitan area, with temperatures in the Sierra reaching up to 37°C [7].

Key catalysts include the continuation of the heatwave, which authorities expect to remain above 40°C until at least 7 July, suggesting a high likelihood of sustained extreme conditions through the settlement window [2]. Emergency services are on high alert due to the risk of heat exhaustion, and the dry, cloud-free conditions with uninterrupted sunshine provide the perfect meteorological setup for record-breaking afternoon peaks [2]. The dependency on the specific Barajas Airport station reading remains critical, as regional variations exist, but the widespread nature of the 2026 European heatwaves indicates that the airport station will likely reflect the broader extreme temperatures affecting the capital [5].
