Kumamoto in April After the blossoms, the castle grounds turn fresh green. Wet days dip slightly from March. Golden Week starts in the last days of the month and domestic travellers arrive, so queues at the castle can grow.
Highs averaged 22°C and lows 11°C, an easy range for walking around all day. An 11°C gap between afternoon and night meant dressing twice: once for the day, once for after dark. Rain fell on 10 days of the month on average. Most years sat near the average of 10, though 2011 dipped to 6 and 2015 climbed to 15.
The coldest night came in 2025, at 2.3°C.
