What is known about the Bismarck Sea?
Madang, Papua New Guinea © Harald SchröderThe Bismarck Sea, located off the northern coast of Papua New Guinea, is known for its warm, tropical waters year-round. The temperature of the sea remains consistently high, ranging from 79–84°F (26–29°C) throughout the year. This makes it an ideal destination for those looking to swim or enjoy water activities in comfortable conditions. Whether you're visiting the coastal areas near towns like Madang or the islands of New Britain, the warm waters make swimming and snorkeling popular choices for locals and tourists alike.
During the dry season, which typically spans from May to October, the Bismarck Sea sees less rainfall and calmer seas, making it an even more inviting spot for swimming. The rich marine life and clear waters around the reefs further enhance the appeal of the sea for snorkelers and divers. While the Bismarck Sea’s water temperatures remain pleasant throughout the year, the most popular time for tourists to swim and explore the marine environment is during the dry months, when conditions are at their most favorable for beach and water activities.
