About Guarulhos in September
Guarulhos north of São Paulo hosts the main international airport and experiences unique microclimate effects from flight operations and the Serra da Cantareira's northern slope. The Serra acts as a barrier that concentrates rainfall on its southern face above Guarulhos.
