石垣岛 3月 天气

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.

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.
