Hi
I would like to suggest Andaman. September is the best time to visit Andaman. - Its the best gateway for any one travelling from city. One can experience complete tranquility and peace. - If you are foodie then its a feast. Major attraction is Sea food. One can try different kind of dishes may be fishes, lobsters,prawns and crabs. - Then enjoy the bunch of adventure activities and water sports. It provides various kinds of water sports such as Scuba diving, Sea walk, Snorkeling, Kayaking and many more . - Do some sightseeing and visit numerous islands.

Hi Chandni, mid-September is not a good time to visit Andaman nor Phuket. Due to monsoon, both places face heavy rainfalls. October to February is the best time to visit Andaman. As for September, Kovalam, Tarkarli, Goa and Kerala are better beach alternatives.
