Kagoshima's climate at a glance
Kagoshima is warm for mainland Japan: January highs average 13.1°C and frost is rare. The rainy season (about 30 May to 15 July) is intense, with June averaging 570 mm of rain, among the highest monthly totals of any major Japanese city.
Summers are hot at around 32°C, and typhoons often approach from August to September. One local extra: Sakurajima erupts regularly, and in summer the wind tends to carry its ash toward the city.

October to May is the most comfortable stretch. Cherry blossoms open around 26 March, and autumn colour arrives late, around mid-December. Winter is ideal for the sand baths and onsen at Ibusuki and Kirishima.
Tips

- Avoid planning island trips to Yakushima during June's heaviest rains if you want to hike.
