Best time to visit Rio de Janeiro
No month in Rio de Janeiro can be tested against our rule: there is no daily high. Not published: the city's cell is sea, and a moved cell failed our station test. Daily lows run from 16.4 °C (61.5 °F) in July to 23.4 °C (74.1 °F) in February, as 1991-2020 model estimates; figures in brackets are converted.
Rule: daily high over 16 °C and up to 28 °C, low 8 °C or more, rain 150 mm or less. Means hide hot, cold and wet days. No data on crowds, prices or events. How we test each month
