Did the cool season arrive in North Thailand?

Destination Travel Guide Nan, North Thailand
 

Since a few days the evening, nights and mornings are cold in Pua, North Thailand. Well cold is of course relative, for me it feels cold and in the early morning I am wearing an extra warm shirt. In day time it is again bloody hot, with total blue sky. Due to the big temperature differences the morning are also beautiful with low hanging clouds / fog. And it stays cool until about 10:00am or 11:00am. Does this mean the cool season has arrived early? I hope so although the weather forecast is next week some rain again. And actually the rain is needed here in North Thailand. For more information about Nan province see Destination Travel Guide Nan.
