The Ganges and Brahmaputra delta, the largest river delta in the world, dominates Bangladesh, with hills in the southeast and a long coast on the Bay of Bengal. Dhaka, the Sundarbans mangrove forest and the tea estates around Sylhet are its best-known places. The cool dry months from November to February are the most comfortable, the weeks before the monsoon bring heat and thunderstorms, and the monsoon from June to October soaks much of the country.
