Climate in Alcala de Henares

Alcala de Henares, in the Henares valley east of Madrid, has a continental-influenced Mediterranean climate similar to the capital but with colder winter nights due to temperature inversions over the river.

Summer highs top 35 degrees Celsius in July and August, and winters are cold with frequent morning frosts. Diurnal range is wide, especially in summer.

Annual rainfall is around 410 mm, concentrated in spring and autumn. Afternoon storms fed by the Sierra de Guadarrama can cause local problems in low-lying districts near the Henares.

Best time to visit is spring and autumn. Use the hourly forecast and feels-like temperature before planning the Cisnerian University, the Cervantes House Museum or the storks nesting on its bell towers.
