Meteo Miyakojima (Miyako) in novembre

Regulars are direct this counts as a genuine gamble month, the official typhoon season running June through November with most storms actually hitting in July, August, September and October specifically, real potential for arrival or departure delays. Our row backs that hot, genuinely wet read, 31.8C reading as a scorching 37C, over 26.5C nights feeling 30C, with a substantial 232.2mm of rain across 17.3 days and a real 27.7 kph wind. Regulars are consistent March and October are named as the actual best months here, coolest and driest by comparison, this month instead bringing the summer's full heat and humidity on top of the storm risk. Underwater visibility for snorkeling can also take a real hit when rain moves through. The sea sits at a bath-warm 30.1C. The record: 10.5 hours of sun, humidity 82 percent and AQI 39.

May opens the rainy season on this chain of islands, and regulars are quick to distinguish it from the mainland version: it rains neither every day nor all day, more often a one or two hour downpour followed by sun, though some stretches bring lots of drizzle instead and the pattern really cannot be predicted in advance. Our row backs the shift with 227.1mm across 15.9 days at 82.8 percent humidity, while temperature stays comfortable, 28.2C reading as 32C over 23.3C nights. The board's peak recommendation is March or October, the coolest and driest months, but they are clear May is still visitable rather than a month to avoid. The sea is 26C. Typhoons belong to September, not now. The record: 9.6 hours of sun, a 27.9 kph wind and AQI 57.

March counts as a peak month here for reasons that have nothing to do with getting in the water. Regulars name it among the coolest and driest of the year and place it in the typhoon-free spring, which is what makes it comfortable to travel in. The sea is the catch: still wintry, still cold enough that anyone coming for a beach holiday is pointed at April at the earliest, and the windy stretch has not finished either. Our row backs both halves - a 32.8 kph average wind and a 22.9C sea, under 23.1C days and 18C nights that feel like 15C. Driest is relative: 123.1mm still falls, across 12.8 days. The record: humidity 73 percent, 8.1 hours of sun and AQI 58.

Regulars rate Miyako's beaches the best in Japan and July among the worst times to see them: very hot and very humid, with the warm sea making it worse rather than better. Our row is the evidence - 32.1C reading as 38C, nights of 26.7C that feel like 30C, 82 percent humidity and a sea at 29.5C that offers no cooling at all. The other summer risk on the Ryukyus is logistical: typhoons are frequent and can delay an arrival or a departure by days, which matters more than the rain itself, though our 164.7mm across 14.4 days is substantial. March and October are the months they name instead. People who came in July still enjoyed it, with plenty of cold drinks. The record: 11.2 hours of sun, a 31.1 kph wind and AQI 35.
