This section was written by a language model from the climate figures above, and nobody has checked it. The month-by-month table is measured — ten years of ERA5 readings and published holiday calendars — and where the two disagree, the table is the one to believe. The busiest and quieter periods here also count toward the crowd score, which is 20% of the ranking.
