Weather in Rio de Janeiro

Best time to visit

In Rio's summer (December to February), temperatures regularly reach 40ºC (104ºF) or more. When the heat is on, tourists should follow the Brazilian example and hit the beach rather than rush around. These months are also peak season - not only are international flights more expensive, but domestic travel and hotels are charged at a premium and get booked up quickly.

Rio’s winter is never that cold, with temperatures rarely reaching below 17°C (63°F). On cooler evening and during its winter months, June to August, bring a light sweater or jacket.
