Exactly, there simply is not a best time to visit Thailand.
At any time there is a region where it is good weather.
Most people just do not realize how different the far south where I am now is from the north, and how different the weather is.
It is not only over 1200 kilometers, or 1500 by road, it also is a complete different climate.
Allthough this time of year here in the deep south certainly not is the best, it is good to escape the cold and wet winter weather from Netherlands.
January till March are normally better weather here, after that it will be very hot
