Naha in June

The rainy season ends in mid to late June, and the end date varies a lot by year. June 23 is Okinawa Memorial Day, treated like a public holiday in the prefecture, with a memorial service held in Itoman. Once the rains lift, the sun turns strong.

Days averaged 30°C and nights 25°C. Midday was for air conditioning, a cold drink or a long lunch out of the sun. With just 5°C between afternoon and night, the evening felt like a continuation of the day. There were 13 rain days on average, roughly every other day. Averages hide a lot here: one year saw 5, another 21.

With 15 days above 30°C on average, most of the month felt like high summer. Wet days did not mess around: about 25 mm each, the kind of rain that drives you into a doorway.
