About Retiro in September
The 125-hectare Parque del Retiro acts as Madrid's primary green lung, creating a measurable cooling island that lowers surrounding temperatures by 2–4°C during summer afternoons through evapotranspiration. The park's large artificial lake and mature tree canopy generate cool air that drains into adjacent residential streets, particularly noticeable on calm summer evenings.
