Phuket diving weather in September
September is statistically the wettest month in Phuket so if you are worried about getting rained on while on holiday you should avoid this sodden month.
If you are coming in September and want to dive the best plan of action is to wait until you are here in Phuket and check the short term weather forecast before you book.
It is not necessary to book Phuket day trip diving months in advance, there will always be space available at this time of year. Check the weather forecast the day before.
