Decreasing rainfall is a defining characteristic of September’s weather in Rio de Janeiro, marking a transition from the wetter winter months to the drier spring and summer seasons. This shift in precipitation patterns significantly impacts the city’s climate and overall atmosphere.

The southward migration of the Intertropical Convergence Zone (ITCZ), a band of low pressure around the equator, reduces the frequency of heavy rains that characterize the winter.
