Louie:
Please set the record straight once and for all! Some of us are confused.
I was under the impression that it is high season(good weather, clear visibility) now in the Gulf of Thailand and that it was monsoon season on the Andaman side.
I have heard reports that I've in fact got it backwards.
So who's right?
Here we go again..
In really really general terms.
Andaman Sea - November - April is the best time
Gulf - May - October is best
Date today? May 19th. Weather in Phuket? Really hot and sunny..perfect diving conditions. Customers in the door..zero.
The westerly wind has just started blowing in the last week, so the weather is changing over from hot season (especially March/April) to the South West Monsoon season. Now the word Monsoon is what confuses people. You hear it and think "hurricanes, typhoons, rain all the time, dark, gloomy, mudslides". Actually the word refers to wind and not rain. The months from May to October in this area (Phuket) are wetter than November to April. But there is still more good weather than bad. Just don't expect calm seas and sunburn every day. :mostlysun
Same goes on the Gulf side during the "North East Monsoon", can be cr*p or can be quite nice. We can only generalise and then argue about it.

(and yes that's a web site from one of our competitors! Mind you, John Williams co wrote the Lonely Planet book on diving in Thailand, so it's worth reading)
General weather forecast, try the BBC :

Gee, I hope that helps you and un confuses you.
