Koh Phi Phi Weather In September

Monsoon season comes into full effect on Koh Phi Phi in September. While it won’t be raining all the time, you can expect prolonged downpours and strong winds too.

If you wondering about Koh Phi Phi weather in September, be advised it’s not for everyone.

The bad weather also means that crossing to Koh Phi Phi can be hazardous due to rough seas. Think twice about taking a speedboat from Phuket or Krabi to Koh Phi Phi in September. It’s much safer to take a ferry as they are bigger vessels with more stability.

On Koh Phi Phi itself it can be difficult to go and visit Maya Bay and the other famous attractions around the island due to rough seas – if the weather is bad it’s too dangerous for longtail boats to take tourists out.

Similarly dive boats are limited as to where they can go by the weather. There a few protected sites but trips might be cancelled.

The upside of the variable weather on Koh Phi Phi in September is that hotel rates are very cheap during this month and there’s a hard core crew of people here to party. If you don’t mind taking your chances with the weather and are not bothered about whether you see Phi Phi’s famous attractions like Maya Bay it can still be fun, but for many people, September is not a good time to come to Koh Phi Phi.
