Diving in Sumatra has treasures to behold and offers a personal experience as dive sites are less crowded. Pulau Weh is the highlight. This small volcanic island is a tropical paradise with white sand beaches. Blessed with great visibility that extends to 40m, diving at Pulau Weh consists of wall dives, coral gardens and boulders. Outer reefs offer exciting drift dives.
Another dive destination in Sumatra is Padang. Visibility is about 15m closer to land but further out, there are some beautiful pinnacles in the open sea. Macro dives are plentiful and underwater conditions are typically easy and calm, suitable for new divers. The third area for diving is at the Riau Archipelago where there are healthy coral reefs and sandy bottoms to explore for critter hunting.
Timing is crucial for scuba diving in Sumatra, with the dry season from April to October providing calm seas, good visibility, and ideal conditions for exploring reefs and drop-offs. The wet season brings occasional rain and stronger currents but can also attract large pelagics like manta rays. Water temperatures remain warm year-round at 27–30°C, making it suitable for all divers. Wildlife encounters, visibility, and current conditions should guide planning for Sumatra diving adventures.
Accessing Sumatra’s dive sites usually begins via Medan’s Kualanamu International Airport or Banda Aceh Airport for northern destinations like Pulau Weh. From the airport, short domestic flights, ferry rides, or private transfers reach key dive hubs. Pulau Weh is typically accessed by a 45-minute ferry from Banda Aceh, while Nias and Banyak Islands require longer boat trips from mainland ports. Local dive operators provide gear, guided dives, and transport to remote reefs. With careful planning, Sumatra diving is an unforgettable experience in Indonesia’s hidden marine paradises.
