Peleliu sits in the Western Pacific Ocean at the southern edge of Palau's main island group, and its diving is defined by strong, dynamic currents that sweep along walls and past exposed corners. All sites are reached by boat, accessible from Peleliu Island or via liveaboard. The site list runs from shallow reef to very deep wall terrain, and includes two significant wrecks, the USS Perry and the Iro Wreck. Sites such as Peleliu Express, Peleliu Corner, and Peleliu Tip are firmly in advanced and technical territory, demanding drift experience, solid buoyancy control, and awareness of down currents. Species recorded here include whitetip reef sharks, Napoleon wrasse, whale sharks, bluefin trevally, and green sea turtles. The southeastern wall faces the deep water of the Palau Trench and is known for annual spawning events including those of the sailfin snapper.
Monthly water temperature across Peleliu's sites, from satellite sea-surface data corrected for depth. The band shows the site-to-site spread.
Water temperatures sit in the upper twenties to thirty degrees across all months, with slightly cooler minimums early in the year. This range means exposure protection is comfortable rather than essential, though longer technical dives on the deeper walls may warrant a light wetsuit. Currents are the dominant variable here and can shift rapidly with the tide, so timing dives and briefing boat pick-up points carefully is not optional.
Water temperature around Peleliu ranges from about 28°C in January to 30°C in July, based on satellite sea-temperature data for its dive sites.
With water around 28–30°C, a rash guard or 3mm shorty works in Peleliu year-round.
