Rain days are the days with at least 1 mm of rain, as a weather station counts them.
Weather read at Nan town: ten years of ERA5 and ERA5-Land reanalysis, through Open-Meteo's open data.
A busy month is a crowded one, not a bad one — usually it is crowded because the weather is good. It is flagged rather than scored down, and crowds alone never make a month “avoid”: that is reserved for weather worth skipping.
