have been twice in July. Beautiful weather. You will get rain but it is almost early early evening or late afternoon- when you have had enough sun for the day anyway

I have been to KS in July three times, always had great weather.

Went last July. Had about 2 x 2 hour rainy spells over a 10 day period!

Noticed a massive change in the amount of people on Samui pre and post July 10th ish though, earlier the better i'd say for that reason!

eeeek! we get married on the 17th july so probably wont be going till around the 19th/20th! Do you think the weather will still be ok-ish in the last couple of weeks in july/first week august?!

I see that this post i a bit off time already but still I want to write to let others now that the summer on Samui are usually very good. But as anywhere you can get sun when least expect and rain when least expect. As said before in the thread it is common that it sometimes rain in the evening or in the nights.
