Hi Rupesh. It is not all that advisable to visit Andaman Islands in June. During this time, there is a lot of rainfall and you may even face tropical storms. Moreover, water sports and activities like scuba diving and sea walking will be closed due to volatile water conditions. A better time to go would be a few months early, in April or May or anytime between November and May. You can check out these holiday packages for options and details. Happy Travelling!
