  2. フジャイラ市 🇦🇪 アラブ首長国連邦Gulf of Oman dive season · 10月15日〜5月15日（例年）Snoopy Island and the Dibba wrecks are at their clearest in the cooler half of the year; summer plankton blooms cut the visibility badly.92
  3. キーシュ島 🇮🇷 イランDiving and beach season · 10月15日〜5月10日（例年）The water is clearest and the air bearable in the cool half of the year, which is when the dive operators and the glass-bottom boats actually run properly.91

  8. ジブチ 🇩🇯 ジブチWhale sharks in the gulf · 11月1日〜2月15日（例年）Plankton blooms in the Gulf of Tadjoura pull in a crowd of unusually young whale sharks, most of them only three or four metres long.79

  12. モンバサ 🇰🇪 ケニアWhale sharks off the coast · 12月1日〜3月31日（例年）Whale sharks move along the Kenyan coast through the northeast monsoon, and the boats that go looking for them run out of Diani and Watamu rather than Mombasa itself.72
  13. ランター島 🇹🇭 タイ王国Hin Daeng and Hin Muang season · 11月1日〜4月30日（例年）The deep pinnacles two hours south are the reason people come here to dive, and the boats only run in the settled months.71

  16. ヴィランクーロ 🇲🇿 モザンビークWhale sharks and mantas · 10月1日〜4月15日（例年）Whale sharks and manta rays gather around the Bazaruto channel from October through to April, a window that overlaps with the archipelago's hottest and wettest months.62
  17. Tofo 🇲🇿 モザンビークWhale shark season · 10月1日〜3月15日（例年）Whale sharks gather off the reef from October to March, most reliably in December and January when plankton blooms bring them close enough for the ocean-safari boats that launch straight off the beach at dawn.61
  18. チューク州 🇫🇲 ミクロネシア連邦Calm months on the wrecks · 12月1日〜4月30日（例年）The north-east trades settle the lagoon from about December to April, which is when the crossings to the far wrecks are comfortable and the water inside the holds is at its clearest.56
