Bali Sea Water Temperature Today & Regional Overview
We find every place where you can swim and show you the water temperature there today and throughout the year.
Current Water Temperature
The water temperature in the Bali Sea today ranges from 28.2°C (Nusa Dua, Indonesia) to 29.2°C (Banjar Bali, Indonesia).
As of today, the minimum water temperature in the Bali Sea is above 82°F (28°C). This is very warm water, which may feel almost hot to most people. Swimming in such conditions is perfect for those seeking relaxation and comfort in the water. These waters are often preferred for relaxation in hot weather, as the water temperature does not cool the body significantly. However, it is important to remember that in such warm waters, caution is necessary, as prolonged exposure without rest can lead to overheating.
It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

The Bali Sea, the tropical waters north of the island of Bali, maintains warm conditions year‑round, making it inviting for swimming. Surface temperatures typically range from about 26°C during the coolest months to around 30°C at the warmest. Seasonal variation is modest: during the dry season (roughly May to September) temperatures commonly sit near 26–28°C, while in the wet season (roughly October to April) the sea tends to be slightly warmer, often 28–30°C, with the highest readings around late summer. Because Bali lies close to the equator, daily and monthly swings in water temperature are small compared with higher latitudes, so visitors can expect comfortably warm water almost anytime of year.
Swimming Conditions
Swimming in the Bali Sea is widely allowed and popular along many beaches and in sheltered bays. The warm temperatures make extended swims pleasant, and many coastal areas are well suited for snorkeling and recreational swimming. However, local conditions affect safety and enjoyment: some stretches have strong currents, rip tides, boat traffic, or extensive reef and rock areas that require caution, and water quality near urban or river mouths can vary after heavy rains. Lifeguard coverage is not uniform, so swimmers should heed posted warnings, choose patrolled beaches when possible, and be mindful of weather and tide changes. In general, the sea’s consistently warm temperatures make swimming feasible year‑round, provided basic safety precautions are followed.
