Nagasaki in July The rainy season winds down into sticky days. Nagasaki's record-wettest month was a July, and downpours near the end of the rains do happen in some years. When it clears, the summer heat arrives at once.
It was a hot month: 31°C by day and 25°C after dark. There were 11 rain days on average, roughly one day in three. Year to year it swung widely, from 4 rain days in 2011 to 18 in 2020.
Highs topped 30°C on 20 days of the month on average. Mixing in indoor stops at midday made sense. July 2025 averaged 33.3°C by day, 2.6°C above the 20-year mean. Each rainy day brought about 27 mm, closer to downpours than drizzle.
Typhoons i 6 of the last 20 years had a tropical storm pass within 300 km this month.
