The month of August brings about torrential rains with the monsoons being at their peak in Andamans. Though the entire Andamans are a little dull during monsoons, one can catch steal deals on flight and hotel bookings. If you don't mind heavy rains and are just looking to unwind, go ahead and plan a trip! If not, please plan one post October.
Hope you have a great trip! :)
