I've booked a ticket to Phuket from 3rd September - 19 September 2018.
Can anyone give me the heads up in terms of weather, as this is meant to the thunderstorm month.
Yep, you guessed it, thunderstorms
One of the two wettest months of the year.
I have been in September. Sometimes it rained all day, other days just a downpour for a hour or so.
