Best time to visit Fukuoka

October is the best month in Fukuoka, scoring 81 out of 100, with August the weakest at 39. The 42-point spread means timing is worth planning around without being decisive. 4 of the twelve months sit within ten points of the best, so there is more than one right answer.

August is the warmest month at 32.1 °C and January the coolest at 9.3 °C — a 22.8 °C spread across the year. Around 60 days a year top 30 °C, concentrated in August and the months either side. 21 nights a year dip below freezing.

There is a real wet season here. June to August carry the rain — up to 18 wet days in a month — while January, February, April, May, October, November and December drop as low as 9. That 9-day gap is the biggest single difference between a good month and a bad one in Fukuoka, 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, April, May. The one to think twice about is August. Each month below has its own page with rainfall reliability, extremes, daylight, sea temperature and crowd levels.
