Palau Rock Islands in October

November through May offers the sweet spot — less rain, calmer seas, and visibility that can hit 200 feet underwater. December and January see the least rainfall, making them prime for diving and snorkeling. Water temperature hovers around 82°F year-round. The trade-off? These dry months also bring higher prices and crowded dive sites. June through October brings afternoon thunderstorms and choppier waters, but you'll have popular spots like Jellyfish Lake more to yourself. Typhoon season technically runs June to December, though direct hits remain rare. Book dive trips early during peak season — operators fill up fast. And remember, Palau sits just north of the equator, so seasons don't mean much beyond wet versus dry.
