Current forecast models from Spain’s national meteorological agency indicate a daytime maximum near 22°C in central Madrid under stable high-pressure conditions and light northeasterly flow, aligning with the market’s 99.5% implied probability for that exact outcome. This consensus draws on ensemble runs showing minimal deviation from the seasonal mid-May average of 21–24°C, with no significant warm-air advection or clear-sky radiative heating expected to push readings higher. Traders appear to discount the small remaining uncertainty in official station measurements, which could shift by 1°C if afternoon mixing or localized urban effects intensify. The market will resolve once the day’s official maximum is recorded, with any late-day model update representing the primary remaining catalyst for movement.
