UV index at 11.8 in Fukuoka means extreme risk: limit outdoor time especially from 10 a.m. to 4 p.m., actively seek shade, wear protective clothing, broad-brimmed hat, apply SPF 30+ sunscreen every 2 hours, and wear UV-blocking sunglasses. Watch for bright surfaces like water and snow increasing UV exposure.
Fukuoka's UV index is moderate to high, especially in summer months when it can reach levels above 7, posing a stronger sun exposure risk during peak daylight hours. The city experiences four distinct seasons: warm, humid summers with frequent rain, mild and dry winters, a colorful spring with cherry blossoms, and a cool autumn with less rainfall. Compared to the wider Kyushu region and nearby countries like South Korea and China, Fukuoka has a milder winter and more rainfall during the rainy season, but a similar hot and humid summer climate.
