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 Aspen, 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.
