You can pack lightly for a trip to the Andaman Islands – the weather stays comfortably warm year round, being a tropical climate that changes very little from month to month. Bring along a bathing suit, beach shoes, hat and sunglasses, as well as possibly pack a light jacket and umbrella for cool evenings and rainy days. Depending on the time of the year, you can experience rain-free hot, sunny days and warm nights on your vacation, or off-and-on cloudy skies and rain showers in the morning followed by magnificent colorful sunsets.

There are not true ‘seasons’ in the Andamans – the amount of sunshine or rain determines what season it is in certain months of the year (and sets the prices at the hotels and resorts). The hot, sunny months are the most popular times to visit the Andamans, with the most tourists, crowded attractions and higher prices. The remaining months when the much-needed rains arrive are quieter and not always as ‘wet’ as one would think, and can be a very economical and pleasantly relaxing trip for the visitors who want to experience the islands in a different way.


Just as in other tropical island locations around the world, the Andaman Islands measure their days and nights by the movement of the wind and the tides. Located in the Bay of Bengal and the Andaman Sea, these islands depend on the monsoon rains for irrigation, agriculture and as their main freshwater source, and the locals are glad to see the welcome rains return to refresh the island forests, streams and reservoirs. Approximately 120 inches (3,000 ml.) of rain falls on the Andamans each year.

Beginning in late May and ending in mid-September, monsoon showers flow in on southwest breezes to bring frequent rain to the islands. The months of June, July and August see the heaviest showers, and rarely a tropical cyclone may blow through. Some watersports could be affected, as well as inter-island transportation – you’ll find it is not going to affect your vacation every day – but occasionally the ocean will be too rough and tour boats will not depart the docks. Many tourists who are not interested in scuba or snorkeling find visiting during these months to be very enjoyable, as many of the land-based attractions are open year-round and there are fewer crowds at the popular beaches, like beautiful Radhanagar on Havelock Island..


As September passes into October and November, the monsoon rains will lighten up and bring intermittent showers on a northwest breeze, providing partly sunny days with cooler evenings, lush tropical greenery, and increasingly clear blue skies and calm seas throughout the islands. December, January and February are the busiest months of the year,when the majority of tourists visit the islands to enjoy watersports, natural attractions and local festivals. December through April is the best time to travel through the islands to experience the sea turtle sanctuaries, observe native birds in the forests, or enjoy the seasonal trips to view the spectacular coral reefs at Mahatma Gandhi Marine National Park, as there will be less humidity, warmer daytime temperatures and very little chance of rain.
