Hanoi Weather, Best Time to Visit

Hanoi is located in the Red River Delta in northern Vietnam. The capital of Vietnam has a tropical monsoon climate: summer from May through July, autumn from late August through October, winter from mid November through February, spring from February through April.

 It is often cold and dry during the winter months but there may be light rains for a couple of days each time a new spell of Cold Northeasterly Monsoon hits the capital city.

From February through March there may be light rains (rain dusts) in Hanoi which makes the air quite damp. The most serious moist air can be found at the end of March and at the beginning of April. It may get foggy during this time.
