The climate of Ha Long is mainly tropical monsoon with a hot - humid summer in between April and October and a cold – dry winter in the other months. And as major tourism activities in Ha Long are involved in ocean and island tourism, the good time to come to this place should be in the summer time so that travelers are able to try all services and activities in here. Also, this is the time for some attractive and colorful festivals such as the Ha Long Tourism Festival in April or Ha Long Carnival in May. One more suggestion to you is not to visit Ha Long Bay in January or December due to the fact that they are the coldest months in a year.
