The idyllic Radhanagar Beach on Havelock Island, also known as Swaraj Dweep in the Andaman and Nicobar Islands, is best visited during the months of October to May. During this period, the weather is predominantly sunny with clear skies and a pleasant temperature range, making it an ideal time to soak in the sun and enjoy the beach's beauty. The monsoon season, extending from June to September, is generally avoided by tourists due to heavy rainfall, strong winds, and rough seas which could hamper beach activities and travel plans.
Outside of the monsoon season, Radhanagar Beach emerges as a tropical paradise showcasing its turquoise waters and powdery white sands to the fullest. The months of November to February are particularly sought after, as the climate is comfortable for beach outings, water sports, and exploring the island's rich coral reefs and marine life. During this peak season, you’ll find the beach and the island bustling with tourists, while the period from March to May, although slightly warmer, offers a more relaxed atmosphere and equally enjoyable experience, with fewer crowds and uninterrupted serenity.
