Rain days are the days with at least 1 mm of rain, as a weather station counts them.

Weather read at the centre, 19 km from the airport (NGS): 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.

How busy it gets

Busiest in August; quietest in January, June and September.

Then and now

Nagasaki's July days now average 29.8°C, 3.0°C warmer than in 1981–1990. 11 of 12 months are clearly warmer.
