Best time to visit Kitakyushu

October is the best month in Kitakyushu, scoring 81 out of 100, with January the weakest at 45. The 36-point spread means timing is worth planning around without being decisive. Only 3 months come close to the top, which makes the timing narrow.

August is the warmest month at 29.5 °C and January the coolest at 9.2 °C — a 20.3 °C spread across the year.

There is a real wet season here. July to August carry the rain — up to 18 wet days in a month — while May, October and November drop as low as 9. That 9-day gap is the biggest single difference between a good month and a bad one in Kitakyushu, and it moves further than the temperature does.

The sea is comfortable for swimming in June to October — 27.4 °C at its warmest against 14.4 °C at its coldest. The water peaks a month or two after the air does, so the best swimming falls later in the year than the best weather. Daylight runs from 9.9 hours in winter to 14.4 in summer, enough to notice on a sightseeing itinerary.

The three strongest months are October, May, September. The one to think twice about is January. Each month below has its own page with rainfall reliability, extremes, daylight, sea temperature and crowd levels.
