AEMET's latest forecast, drawing from ECMWF and national HARMONIE model consensus, projects a maximum temperature of 24°C at Adolfo Suárez Madrid-Barajas Airport—the probable resolution station—for April 8, driving trader consensus to a 100% implied probability on 14°C or higher. Yesterday's observed high there reached 22.6°C under similar high-pressure dominance, with light easterly winds and mostly clear skies fostering rapid daytime heating above the April climatological average of 18°C. Current morning observations already exceed 14°C, minimizing downside risk. Realistic challenges would require an unforeseen cold front or persistent cloud cover disrupting solar insolation, though models show no such signals; watch AEMET's hourly updates through afternoon peak heating around 4 p.m.
