The Bay of Bengal is a warm tropical basin with sea surface temperatures that stay relatively high throughout the year. Broadly speaking, winter months (December to February) see temperatures around 25–28°C in northern and coastal areas, while the open southern bay is slightly warmer, typically 27–29°C. Pre-monsoon and the height of summer (March to May) are the warmest period, with surface temperatures commonly reaching 29–32°C, especially in shallow coastal zones and enclosed gulfs. During the southwest monsoon (June to September) localized cooling can occur from increased cloud cover, rainfall and coastal upwelling, bringing temperatures down to roughly 25–30°C in affected areas. After the monsoon, in October and November, waters usually rebound to about 28–31°C as the sea surface warms again.
Swimming Conditions
Swimming in the Bay of Bengal is thermally comfortable for most of the year because the water temperatures generally remain within the range people find suitable for bathing. Whether swimming is allowed and safe, however, depends on local conditions: many popular beaches permit and actively support swimming when seas are calm and lifeguards are present. At the same time, hazards such as strong currents and rip tides, seasonal storms or cyclones, jellyfish blooms, and poor water quality near river mouths or urban runoff can make swimming unsafe at times. Coastal authorities typically advise against swimming during the monsoon and during storm warnings, and choosing monitored beaches and following local guidance is the best way to balance enjoyment with safety.
