    What's the weather like in Koh Tao in December?

    Koh Tao is an island located in the Gulf of Thailand that's often called "Turtle Island" because of its shape. At just 21 km², the island is small but is a popular tourist destination thanks to its paradise-like surroundings and renowned diving spots, which are some of the best in the world.
