Phu Quoc in May The rainy season begins. Mornings are often clear, and clouds build into an afternoon shower on many days. Boat tours are safer if you leave early in the morning, and it helps to keep an indoor option for the afternoon.
It was a hot month: 32°C by day and 26°C after dark. About 14 days a month saw rain, enough that a wet-weather plan was worth having. Averages hide a lot here: one year saw 5, another 21.
31 days past 30°C made it a month for early starts and a long lunch indoors. Each rainy day brought about 18 mm, closer to downpours than drizzle.
