Vietnam Mekong Delta, as a region, lies immediately to the west of Ho Chi Minh City, Saigon roughly forming a triangle stretching from My Tho in the east to Chau Doc and Ha Tien in the northwest, down to Ca Mau and the East Sea at the southernmost tip of Vietnam, and including the island of Phu Quoc, Kien Giang province.
Being a low-lying coastal region, the Mekong Delta is particularly susceptible to floods resulting from rises in sea level due to climate change.
Same with Ho Chi Minh City, the Mekong Delta Region has a tropical climate. The average humidity level is 68%, average temperature is 26 ~ 28 °C. The area is generally warm, and has a rainy season from May to November and a dry season from December to April.
The best time to travel to the Mekong delta is from June to September.
