Naha in July Prime swimming season. The sun is fierce on clear days, so a rash guard and sunscreen are essential. Typhoons are not as frequent as in August but do come in some years, so leave slack at both ends of the trip.
July brought serious heat to Naha, 32°C on a typical afternoon and 27°C overnight. Early mornings were the best time to be outside. Day and night differed by only 5°C, so one outfit worked from breakfast to late dinner. Rain fell on 10 days of the month on average. Year to year it swung widely, from 1 rain day in 2013 to 22 in 2025.
Highs topped 30°C on 31 days of the month on average. Mixing in indoor stops at midday made sense. Each rainy day brought about 22 mm, closer to downpours than drizzle.
Typhoons i 8 of the last 20 years had a tropical storm pass within 300 km this month.
