Recent forecast model consensus from AEMET and ECMWF supports a daily maximum of 25–27°C in Madrid on May 19, driven by clearing high pressure, reduced cloud cover, and southerly flow that enhances daytime heating. These conditions align with current trader sentiment favoring 26°C and 27°C outcomes, as the latest runs project peak temperatures near 26°C under mostly sunny skies with light winds. Historical mid-May averages hover around 23–24°C, making the anticipated warming a modest positive departure tied to stable atmospheric patterns. Updated model guidance expected within 24 hours could refine intensity, while resolution will hinge on official observations from Adolfo Suárez Madrid-Barajas Airport.
