Okinawa Weather Forecast

Earlier than the mainland's, roughly early May to late June. It arrives as heavy bursts between bright spells rather than constant drizzle, and it is followed by July, the hottest and sunniest stretch of the Okinawan year.

August and September are the peak, with the risk running from July into October. A direct hit shuts down flights and ferries for a day or two, so leave slack in the itinerary and take the warnings seriously — the buildings here are designed for it, schedules are not.

The sea holds around 21-23°C in January, which some people will happily swim in, but most beaches close their official swimming season from November to March. Air temperatures near 19-20°C make it mild and windy — a season for walking the beach rather than lying on it.
