    What's the Weather Like in Rio de Janeiro in September

    Rio de Janeiro is one of the most exciting destinations in the world, with world-class celebrations, unrivalled scenery, amazing weather and some of the best beaches in Brazil. Travellers clearly aren't the only ones who appreciate Rios' attraction, with Hollywood blockbusters such as The Incredible Hulk, The Twilight Saga, and the animated Rio all being based in this South American city.

An average low for the month is 19°C, while the average high reaches up to 25°C. Those two temperatures remain basically constant in the course of the month. The overall average day temperature this time of year is 22°C, which is quite high by any means.

    Sea Temperature

    The sea temperature is equally as high as the air temperature, averaging 22°C, making for pleasant afternoon weather for swimming in the Atlantic Ocean.


    Relative humidity is always pretty high in Rio de Janeiro and September is no exception. Humidity levels vary from 54% to 96%, which is definitely, almost uncomfortably, high. Air-conditioning in your hotel room should be a requirement when looking for accommodation.


    September is an average month in terms of rainfall, receiving 87mm in total in the course of 11 days with precipitation. The likelihood of experiencing a rain shower rises as the month progresses. The beginning of the month is the driest part with a 35% chance that rainfall occurs, while the end of the month has a chance of rainfall of 45%. Light rain is the most common type, being observed on 42% of those days with rainfall. Moderate rain, drizzle and thunderstorms occasionally happen as well, respectively on 22%, 20% and 14% of the wet days.


    Cloud cover increases significantly throughout September, from 78%, which already is quite high, to 87%, which is basically as high as the percentage of cloud cover ever gets in this region. The end of September is characterised by mostly cloudy skies.


    This, of course, greatly limits the amount of sunshine that hits the city and its sandy beaches. September has the lowest number of daily sunshine hours per day on average. October, which is a similarly cloudy month, has the same number.
