June - October: The best time to visit Ca Mau is between June and October. This season sees the warmest climate and is the perfect time to soak into the beaches. During the other seasons, the water is generally considered too cold to bathe in.
If you wish to avoid the rains, head to Ca Mau after August, as the rains start to recede then. If less humid and windier weather is your preference, head here in the month of March as the rest of the months are quite hot and humid ranging between 60-85% humidity.
