Crowds is a score out of 100 where higher is quieter. It counts public-holiday clusters in BR as well as at Buenos Aires, 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.
