Fukuoka weather by month
2006-2025, 20 years of records · Not a forecast
Fukuoka gets cold northwest winds off the continent in winter, so skies are often cloudy but rain and snow stay light. In the rainy season from early June to mid July, northern Kyushu is among the wettest parts of Japan, and rain stays heavy through August. Midsummer is sweltering and in autumn tropical cyclones affect the weather. October is sunny and fresh under high pressure. Spring can bring Asian dust. The big Hakata festivals, Dontaku (May 3 to 4), Yamakasa (July 1 to 15) and Hojoya (September 12 to 18), have near-fixed dates, which makes planning easy.
Weighing daytime warmth against rain days, May and October came out as the easiest months. October was the quiet stretch with 7 rain days, against 12 in June.
