Which is the best location to live in Thailand for 3-6 months: Koh Samui, Phuket, Krabi, or Koh Tao?

Probably koh Tao or koh phangnan cause it's going to be rainy season in phuket

Depending on your budget

I read your requirements above, and while I love Ao Nang/Krabi where we live, the rainy season here does suck. And the food options got boring quickly. Also, there's hardly any cool english speakers to meet (the local expat community is very small). We spent a couple of weeks on Phangan recently, loved it and will shift there for a while once this wave hopefully is over.

That being said, if you can handle some rain every day, don't really care about meeting many people the next half year and can pay a bit of a premium for higher end villa/restaurants, then the magic of an tourist empty Krabi is right here. It's pretty f***ing amazing actually. The clouds and sunsets right now are out of this world.

I would recommended phuket personally. You hve all the western conveniences, good supermarkets etc. Only a short drive from Krabi. Samui and the islands are all very dead now.

It really depends on what you are wanting or expecting. From reports on here without tourists Koh Samui is pretty much closed (I realise there are some exceptions and if anyone from Samui wants to correct me I’ll be fine with that). Phuket has areas that are ghost towns but many that are operating pretty much as normal. I guess Krabi is the same. Sorry don’t know the situation in Koh Tao but I suspect similar to Samui.

Why would you leave out koh phangan?

Samui

Remember monsoon season is coming, phuket beaches become great for surfers but dangerous for swimmers.

Personally i like Krabi even though i lived Phuket for long time.

But it all depends what you want.

Koh Yoa Noi is a nice quiet island in Phang Nga bay

Koh Samui very small , Phuket a bit bigger but a bridge and if authorities close it you can not go out which now if you want to go in Phuket you need a covid test , Krabi nice
