Things to do
Travel insurance

Renting a pocket Wi-Fi is the other common way to stay connected.
These are sites people in book with. Each opens in a new tab, on the site's own pages.

Rain days are the days with at least 1 mm of rain, as a weather station counts them.
Crowds is a score out of 100 where higher is quieter. It counts public-holiday clusters in US as well as at Sao Paulo, which is why this table differs from the same one read from another country. A busy month is a crowded one, not a bad one — usually it is crowded because the weather is good. Crowds alone never make a month “avoid”: that is reserved for weather worth skipping.
How busy it gets
The year in Sao Paulo
Sao Paulo's climate features a tropical wet and dry pattern, with the rainiest months being December through February. Travelers should be aware of the potential for heavy rainfall during these months.
| Busiest |
early Dec to late Dec — The festive season attracts many tourists, leading to higher prices.
early Jan to late Feb — Summer vacation and Carnival celebrations boost tourist numbers and prices.
|
|---|---|
| Quieter, still good |
early Mar to late May — Post-Carnival period sees fewer tourists, with more manageable prices.
early Sep to late Nov — The weather is pleasant, attracting some tourists, but prices are generally lower.
|
| Worth timing for |
Carnival, February, movable — Causes infrastructure pressure and price spikes.
|
| Watch out for | heavy rain; humidity |
