Naha in August Typhoons approach Okinawa most often this month. On good days the sea looks its best, but a typhoon can ground flights for days. Around the first Sunday after Obon, an Eisa dance parade is held.
Days averaged 32°C and nights 27°C. Midday was for air conditioning, a cold drink or a long lunch out of the sun. Daily swings were small, about 5°C, with no sudden drop at dusk. With 13 rain days on average, a wet day was rarely more than a few days away. A visitor in 2013 met 6 rain days; one in 2010 met 20. The average of 13 hid that gap.
Highs topped 30°C on 31 days of the month on average. Mixing in indoor stops at midday made sense. Wet days did not mess around: about 21 mm each, the kind of rain that drives you into a doorway.
Typhoons i 13 of the last 20 years had a tropical storm pass within 300 km this month.
