The ideal time to visit Mary's Island in Udupi, Karnataka, is during the winter months, which span from December to February. During these months the weather is particularly pleasant with a cooler climate and minimal rainfall, making it an excellent period for sightseeing and outdoor activities. The temperatures range from 20°C to 32°C which is comfortable for travelers exploring the unique columnar basaltic lava formations that the island is famous for. This is also a great time for photography enthusiasts to capture the stunning scenic beauty of the crystalline rocks against the backdrop of clear blue skies.
Additionally, the post-monsoon months of September to November can also be considered a good time to plan a visit. The island is lush and vibrant after the monsoon revives its greenery. However, visitors should note that boat services to the island are dependent on the weather and sea conditions, and it is advisable to check in advance whether the services are operational. The summer months (March to May) can be quite hot and humid, making it less ideal for some to visit. Meanwhile, the monsoons (June to August) bring heavy rains, which can disrupt travel plans and boat services to the island.
