Upolu is the main island of Samoa and the hub for the country's dive operators, with boats departing from towns including Apia and reaching sites spread around the island's coast. The four reef sites in the database range from shallow coral tops accessible to beginners through to moderate depths that suit intermediate divers, all in the warm South Pacific Ocean. Visibility varies by site and season, reaching up to thirty metres at The Aquarium and between ten and thirty metres at Namua Garden. The resident macro life is varied, including nudibranchs, ornate pipefish, tiger reef eels, clown triggerfish, and octopus. The dry season from May to October gives the most reliable conditions.
