Brazil (Rio de Janeiro) – What you should know
Rio de Janeiro lies at latitude 23°S and has a tropical-humid climate with reversed seasons compared to Europe. The Brazilian summer (December to March) is hot, humid and rainy — the famous afternoon showers are part of daily life, but rarely persist for days on end. Winter (June to September) is more pleasant and drier, with temperatures typically around 21–26°C (70–79°F).
The Carnival in February is Rio's most legendary highlight — but also a climatic challenge: muggy heat, intense sun and frequent thunderstorms can make celebrating outdoors exhausting. The beach days at Copacabana and Ipanema are nonetheless unforgettable.
The best travel time for Rio de Janeiro is May to October: pleasant temperatures (typically 21–27°C (70–81°F)), less rain and clearer air for the spectacular view from Sugarloaf Mountain over the bay. Air pollution is also lower in these months and the sky over the Christ statue usually cloud-free.

The travel year in Brazil (Rio de Janeiro)
December – February
Rio at the height of summer: Carnival (late January / February) is the biggest party in the world — samba schools in the Sambódromo, blocos in the lanes of Santa Teresa and Lapa. On New Year's Eve, millions dressed in white gather on Copacabana beach beneath the fireworks.
March – May
Autumn with beach weather: the rainy season fades, temperatures become more pleasant and the post-Carnival tourist waves have moved on. Ipanema and Leblon without the December crush.
June – August
Rio winter: dry, 25–28°C (77–82°F), the sea a little cooler but fine for swimming. The best weather for trekking up Pico da Tijuca and Pedra da Gávea. The Festas Juninas fill the squares of Lapa with forró music.
September – November
Warm spring: temperatures rise again and the first summer warmth arrives. Beaches and streets slowly fill up ahead of the year's high point.
