I have been looking at weather forecasts but it's very difficult to tell the actual weather. Currently today until Sunday for Bangkok on the BBC weather page has the picture meaning either heavy rain shower or light rain shower. My understanding is that websites usually show the picture meaning "worst case scenario" meaning that potentially there would be a rain shower but only a portion of the day. Is this correct and has this been the reality of Bangkok/Chiang Mai lately?
I am also visiting Koh Samui but am using a blog to look at daily updates.
Currently I am packed for hot weather and so I need to decide if I need to quickly change the type of clothes I'm bringing!
Thank you in advance
