Brazil in October: weather, holidays and where to go

At a glance

Brazil weather in October by city

The figures below are long-term averages from Brazil’s National Institute of Meteorology (INMET) for 1961-1990, published by the World Meteorological Organization. “High” is the average daily maximum and “low” the average minimum.

The contrast with September is sharpest in Brasília: 51.9 mm in September, 172.1 mm in October. The south is still mild, with Florianópolis averaging 22.9 °C by day and 16.9 °C at night, so pack a light jacket if you add Santa Catarina. Manaus, the gateway to the Amazon, stays hot at almost 33 °C.

The UK Foreign Office notes that the rainy season in the south and south-east, Rio included, runs from November to March, and in the northeast from April to July. It also advises following official warnings and avoiding road travel during heavy rain, which is good practice in any month.

Rio de Janeiro in October

October in Rio is warm and fairly settled: 26 °C on an average afternoon, 20.2 °C at night and about 10 days with some rain. The beaches are usable, and the city is between the winter season and the summer rush that starts in December. For a first visit we usually plan Sugarloaf and Corcovado for clear mornings and leave one day of the plan open in case the summit is in cloud.

More detail on each month in the city is on our Rio weather page, and our Rio itinerary shows how we split three to five days.

Holidays and events in October

12 October is the day of Nossa Senhora Aparecida, the patroness of Brazil, a national holiday under Law 6.802 of 1980. In 2027 it falls on a Tuesday, and many people take the Monday off as well, so domestic flights and beach towns near the big cities fill up that weekend. If your dates include it, tell us early.

Beyond that holiday we have not found officially announced dates for big festivals in October 2027, so we do not list any here. The next large event is just after the month ends: the São Paulo Formula 1 Grand Prix, which in 2026 runs on 6-8 November at Interlagos according to Formula 1. The 2027 date will go on our page once Formula 1 publishes it.

Where to go in October

• The northeast coast. With 2 rainy days on average in São Luís and 6 in Fortaleza, October is one of the safest bets for beach weather. São Luís is also the starting point for trips to the Lençóis Maranhenses.
• Rio de Janeiro. Warm days, the sea warming up, and fewer crowds than in summer.
• Salvador. Warmer than Rio, though with more rainy days (14 on average).
• The Pantanal. ICMBio describes May to September as the dry season and the best time to visit, with rains from October to April. Early October can still work; book it as a flexible part of the trip. See our Pantanal page.
• The Amazon from Manaus. Hot, with rainfall rising from 83.3 mm in September to 125.7 mm in October. Our Amazon page covers lodges and river trips.

What to plan before you go

• Sun: in the northeast the daily high is above 30 °C, so plan beach time for the morning and late afternoon.
• Long weekend: around 12 October book flights and hotels earlier than usual.
• Rain in central Brazil: in Brasília and the Pantanal keep a buffer day.
• Entry: check entry requirements on official websites.

What to tell us in your request

• Your dates and how flexible they are
• Number of travellers and children’s ages
• Cities or regions you have in mind (Rio, northeast, Pantanal, Amazon)

• Interests: beaches, nature, food, nightlife, photography
• Language you want your guide to speak

Tours, transfers and boats can be cancelled at no cost up to 48 hours before; multi-day tours up to 14 days before. Terms and payment are set out in the proposal; you pay nothing before you confirm. The other months are on our pages for September and November, and the year as a whole is on best time to visit Brazil.
