Batticaloa experiences a warm tropical climate throughout the year, with temperatures typically ranging between 26°C and 32°C. The dry season, which lasts from April to September, is the best time to explore the lagoon, especially for outdoor activities and boat tours. During the monsoon season, from October to January, the region receives rainfall, adding a cooler and greener charm to the environment. The lagoon remains enjoyable year-round, but visitors should check weather forecasts during the monsoon before planning long boat trips. Early morning and late afternoon visits are particularly pleasant due to cooler temperatures and gentle breezes.
Batticaloa Lagoon is a natural attraction and does not have fixed visiting hours. Visitors can explore the lagoon at any time, but certain times of the day offer a better experience:
• Early morning – ideal for birdwatching, photography, and peaceful nature walks.
• Late afternoon – perfect for boat rides and enjoying the beautiful sunset over the water.
• Late night on calm, moonlit days – best time to listen to the famous “singing fish” phenomenon.
Batticaloa Lagoon is globally famous for its rare and mysterious “singing fish.” This unusual acoustic phenomenon was first documented by British colonial officers in 1907, who reported musical humming sounds coming from beneath the water. Local folklore suggests that the sounds come from fish or underwater life forms that resonate against the lagoon bed or submerged objects. Researchers have suggested that these sounds may be produced by marine species during mating or feeding activities. Whether scientific or mystical, the phenomenon continues to fascinate visitors.
Additionally, Batticaloa Lagoon is famous for its fishing communities, rich marine biodiversity, mangrove forests, picturesque bridges, colonial forts, and peaceful natural setting. It is one of the most photogenic and culturally significant lagoons in Sri Lanka.
