Along the coast, the breeze, blowing onshore and offshore, moderates the temperature. Because of its geographic situation, the city is often reached by cold fronts advancing from Antarctica, especially during autumn and winter, causing frequent weather changes. In summer there can be strong rains, which have, on some occasions, provoked catastrophic floods and landslides. The mountainous areas register greater rainfall since they constitute a barrier to the humid wind that comes from the Atlantic. The city has had rare frosts in the past. Some areas within Rio de Janeiro state occasionally have falls of snow grains and ice pellets (popularly called ) and hail.

Roughly in the same suburbs (Nova Iguaçu and surrounding areas, including parts of Campo Grande and Bangu) that correspond to the location of the March 2012, February–March 2013 and January 2015 pseudo-hail (granizo) falls, there was a tornado-like phenomenon in January 2011, for the first time in the region's recorded history, causing structural damage and long-lasting blackouts, but no fatalities. The World Meteorological Organization has advised that Brazil, especially its southeastern region, must be prepared for increasingly severe weather occurrences in the near future, since events such as the catastrophic January 2011 Rio de Janeiro floods and mudslides are not an isolated phenomenon.
