During this time, the flow in the Mekong River is insufficient to prevent saline intrusion and extensive salinization of waterways happens in the lower Delta. The entire Ca Mau peninsula in the southwest area of the Delta is salinized for about 6 months during dry months because there is insufficient freshwater flow in the river to displace saline intrusion from the southwestern area of the Delta.

  • Rainy Season (from May to early November):

The wet or rainy season is from May to early November, with July and August having the highest rainfall level of the whole year. The rain comes in short but heavy showers, happens mostly in the afternoon and just lasts for one hour or so.
