Weather in Rio de Janeiro

Best time to visit

In Rio's summer (December to February), temperatures can 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 (June to August) is never that cold, with temperatures rarely going below 17°C (63°F). On cooler evening and during its winter months, June to August, bring a light sweater or jacket. Rainfall is at its lowest in winter, especially in July and August, when you might only expect half a dozen days with rain over the month.

Symbols indicate the predominant weather for the day in question, calculated based on a weighting of different types of weather. So if a day is forecast to be sunny with the possibility of a brief shower, then we will see a sunny or partly cloudy symbol rather than a rain cloud. For the purpose of this forecast, 'day' is the entire 24 our period 00:00 to 23:59
The maximum temperature is the highest temperature forecast between dawn and dusk, and the minimum temperature is the lowest temperature expected from dusk on the day in question to dawn the next day. The temperature is in °C, or Celsius.
Wind speed and direction are the conditions expected at midday. Wind direction is based on a 16 point compass. W, SW, SSW, etc. The wind direction states where the wind originates. Wind speed is listed in MPH or miles per hour.

  • 51 to 70 is moderate to low
  • 71 to 80 is moderate
  • 81 to 90 is moderate to high
  • 91 to 100 is high
Pressure is measured in millibars (mb)
