Phu Quoc in September

The rainiest stretch of the year. Sea conditions are poor and island tours can be cancelled. Vietnamese visitors come over the September 2 National Day holiday, but the island is quiet overall.

It was a hot month: 30°C by day and 25°C after dark. The gap between day and night was just 5°C, so it felt much the same around the clock. Rain was a regular part of the month, showing up on 20 days on average. Year to year it swung widely, from 14 rain days in 2014 to 26 in 2012.

19 days past 30°C made it a month for early starts and a long lunch indoors. Wet days did not mess around: about 25 mm each, the kind of rain that drives you into a doorway.

Typhoons i No tropical storm passed within 300 km in this month over the last 20 years. Typhoons: December
