Highest temperature in Madrid on July 22?

Platform comparison

Market context

Madrid is in the middle of a severe summer heat spell, and the market is being resolved off the highest temperature recorded at Adolfo Suárez Madrid-Barajas Airport on the day, not a citywide average. A Spanish weather preview published this morning put Madrid’s maximum at **39°C** with **0% rain** and largely clear conditions, which fits the market’s current lean towards a high-30s outcome rather than a run at the low 40s.[2][3]

The current pricing reflects that pattern: **39°C** is the clear frontrunner at **77%**, with **40°C** next at **21%**.[1] That shape is consistent with recent Madrid heat episodes, when temperatures have repeatedly pushed into the low 40s during strong heatwaves, but usually need the most intense part of the day to line up with very hot, dry air and little cloud cover.[4][5] For a July settlement in Madrid, the key question is often whether the airport station briefly touches the next degree band or tops out just below it.

The main catalysts traders should watch are the official forecast updates and any last-minute change in the heatwave pattern, especially cloud cover, wind, or overnight cooling that could affect the daytime peak. The current report highlights dry, mostly clear conditions, which supports a high maximum, but a small shift in the intensity or timing of peak heating can be enough to decide whether the reading lands on **39°C** or **40°C**.[2][3]
