Traveller notes on Kagoshima in June
Other months in Kagoshima
Kagoshima's forum calls Kyushu genuinely warmer than the rest of Japan in October and November, warm early in the month cooling toward the end. Regulars flag October as still within typhoon season, occasionally bringing a day or two of heavy rain before conditions return to normal, and recommend a light jacket for the cooler evenings that develop later in the month.
