The Madrid region features the rare Continental Mediterranean climate (Köppen Csa) with cool winters due to altitude, including sporadic snowfalls and minimum temperatures often below freezing. Summer tends to be hot with temperatures that consistently surpass 30 °C (86 °F) in July and August and rarely above 40 °C (104 °F). Due to Madrid's altitude and dry climate, diurnal ranges are often significant during the summer. Precipitation, though concentrated in the autumn and spring, can be observed throughout the year.
