Forecast models from agencies like Spain's AEMET and international ensembles indicate Madrid's June 18 maximum will likely reach 34–36 °C at the Adolfo Suárez Madrid-Barajas Airport station used for resolution, with 35 °C and 36 °C outcomes trading near parity due to small differences in predicted peak timing and boundary-layer mixing. Persistent high pressure, clear skies, and strong June insolation favor rapid daytime heating over the central plateau, while light easterly flow limits advection of cooler Atlantic air. Recent observations show temperatures 2–4 °C above the long-term June average, sustaining the tight spread. Updated afternoon soundings and any late adjustments to surface wind or cloud cover could tip the final reading between the two leading bins.
