In Dry season, the East side of the island takes the impact of Northeast monsoon whereas the opposite side gets truly calm. When Rainy season comes, things seem quite reverse. The Westside gets intensely heavy under the influence of Southwest monsoon.
As you might know, not like many other islands, Phu Quoc has not been getting into freshwater supply problems because it can control the supply of fresh water thanks to the presence of a freshwater river system and streams on the island which mainly lies in the Westside.
South Phu Quoc Island is also the location of the Southern-most town of Phu Quoc as well as the second-largest town on the island – An Thoi town.
This town is located in a stretch of land joining the Southwest side and the South end of Phu Quoc Island.
Thanks to specific terrain, circling-shaped coastline, this area has been becoming a safe shelter to fishing boats in the whole year from the influence of either the Northeast monsoon or the Southwest monsoon. Thereby the town has been developing the largest fishing seaport as well as tourism seaport in Phu Quoc for hundreds of years. The distance between Duong Dong town and the Southern-most town – An Thoi town is around 30 km, until the pre-2011 period when Phu Quoc hadn’t been connected to Viet Nam national electric system, there was only one small dirty lane joining these 2 main towns in Phu Quoc, that lane went through the dense forest and after a period of time of working in Phu Quoc, many fishermen in An Thoi town once told me that they had never reached Duong Dong town until the age of 20 – 30 since many difficulties they probably encountered such as rugged joining lane, for fear of dangerous wild animals, dark lane, long-time trip (almost one day period)…That sounds as if they were living in 2 completely different worlds whereas living on the same island.
