Check the live forecast above for the most accurate view, as Rio de Janeiro’s tropical climate means conditions can shift quickly from bright sun to a heavy downpour, especially during the summer months.
What is the typical weather in Rio de Janeiro by month?
Rio de Janeiro has a tropical savanna climate, meaning warm temperatures year-round with distinct wet and dry seasons. The hottest period runs from December to March, when highs often reach the low 30s °C and humidity is high, with frequent but short afternoon showers. The cooler, drier season falls between June and August, offering milder days in the mid-20s °C and clearer skies, making it a popular time for visitors.
What should I expect from a 10 to 15 day forecast?
Because coastal Rio can see sudden weather changes, a 10-day or 15-day forecast gives a useful trend but not a pin-point guarantee. You’ll generally see stable warmth, though a front can bring a few days of cloud and rain. If you’re checking weather in Rio de Janeiro for 14 days or looking at a 10-day outlook, treat the latter half as an indication rather than a certainty.
Is Rio de Janeiro very rainy in December?
Yes, December is part of the rainy season. You can expect frequent, heavy tropical showers, though they often pass quickly. It remains very warm and humid, so pack light clothing and an umbrella.
Does Rio de Janeiro get cold in winter?
Not by UK standards. From June to August, winter highs are still a pleasant 22–25°C, and nights can feel cooler at around 17–19°C. You won’t need a heavy coat, just a light jacket for the evening.
Is the forecast given in Fahrenheit for Rio?
Most international forecasts for Rio de Janeiro offer both Celsius and Fahrenheit. The live forecast above will typically display Celsius, but if you need it in Fahrenheit, you can often toggle the unit settings on the weather provider’s site.
