Water Temperature Trends
India’s long coastline spans tropical and subtropical seas, so coastal water temperatures are generally warm year-round but vary by region and season. Along the west coast and Arabian Sea, surface temperatures commonly range from about 24–31 °C (75–88 °F), with cooler readings near the northern Gulf of Kutch and warmer values in the south. The Bay of Bengal on the east coast typically stays in the 25–31 °C (77–88 °F) band. Southern waters around Kerala, Tamil Nadu, Lakshadweep and the Andaman and Nicobar Islands are the warmest, often 26–32 °C (79–90 °F), while in winter months (roughly November–February) northern coastal pockets can dip toward the low 20s °C (68–75 °F). Temperatures rise in spring and peak in late summer; however surface warmth during the monsoon season can coexist with rough seas and heavy rain.
Swimming Conditions
Swimming is widely practiced at designated beaches and in protected lagoons, especially outside monsoon periods, and many tourist centers maintain lifeguards and flag systems. During the southwest monsoon (about June–September) and the northeast monsoon affecting parts of the southeast (roughly October–December), authorities often close or warn against swimming because of strong currents, high waves and dangerous rip tides. Local water quality and marine hazards such as jellyfish or pollution also influence whether swimming is advisable. Recreational diving and snorkeling are popular in clear, protected southern areas like the Andamans and Lakshadweep, while casual beach swimming is comfortable most of the year where safety measures and water quality permit.
