Yes, funny topic and headline. Much of the conversations about weather in Thailand center on the hot weather, but it is cold; well very cool and all the talk is of the cold weather. The Bangkok temperature this morning was in the mid-60’s with strong winds, grey skies and a light rain. It was cool enough to sleep with the windows open last night and cold enough that I had to close them.
This is San Francisco weather, not Bangkok weather. Cold weather is happening all over Thailand, especially in the North and Northeast.
The hot season is supposed to be starting, but this is certainly the coolest day I have experienced in Bangkok. As I walked to work this morning the woman that sells me my morning coffee on the street was wrapping her sons arms in plastic bags, he was shivering. Motorbike riders were wearing gloves, people were wearing scarves.
It feels great to me but Thais are not used to the cold weather, their blood is made for the heat and not the cold. The forecast calls for another day of the cold weather and then a return to normal, normal meaning mid-90’s. Off to enjoy lunch outside and enjoy walking around in the cool temps.
Farang ( ฝรั่ง) In Bangkok 
This morning my wife told me it’s really cold outside, I still went out in my t-shirt thinking yeah right… cold in Bangkok… only Thai’s would think that. But actually it was fairly nippy! I cannot remember a day this cold in the last 5 years, what’s going on?
Yes, I wore a coat on my walk to work and felt slightly ashamed at how “soft” I have become. It is cold and it is surprising, but the weather is forecast to hot up again by Saturday and we will remember this cool morning very fondly.
Does anyone know if the cold weather in Thailand has any connection with the disaster in Japan?
Thank you for the good question and comment.
No, the cold in Bangkok has not been tied to anything happening in Japan. The question has been asked and it was a concern raised, but the weather in Bangkok is related to a wind/weather system that is not part of anything happening in Japan. Much of Asia is still very cold, it is just rare for the cold weather to extend into Bangkok, especially at this time of year.
I was in bangkok on the 16th and 17th of March and i was very suprised at the weather.i have been there so many times but i have never experienced cold weather. As usuall i was dressed in shorts and a vest, i got a rude shock when i went outside as it was rainning too. Pretty strange for Bangkok.
