Cuaca Pulau Ishigaki di Juli

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.

Okinawa-region forum posters generally rate October favorably: it's past the subtropical rainy season and still warm enough for snorkeling, with early October running noticeably warmer than the tail end of the month. The consistent caveat is typhoons - October is technically the winding-down edge of the season, and while the odds of a direct hit drop compared to July through September, posters were clear the risk doesn't disappear entirely, so it's worth checking storm tracking before a trip. Expect warm, humid days rather than anything close to cool.

Forum posters describe April as statistically stable and pleasant, sitting before the rainy season and well ahead of typhoon risk - one local source specifically names April (alongside June) as a genuinely good window for that reason. Sea temperatures run around 20-23C, described by posters as fine for tide-pooling and general exploring but on the cool side for comfortable swimming without a wetsuit. The clear trade-off for visiting before peak season: posters report noticeably lower accommodation costs (some citing roughly half of high-season rates), thinner crowds, and especially clear water for snorkeling and diving even without the warmer swimming temperatures summer brings.
