Is it hot in Thailand all year round?

Most parts of Thailand have a tropical monsoon climate and are hot all year round. Take Bangkok as an example. In the hottest April, the temperature can be as high as 37℃, especially in April, sometimes even exceeding 40 degrees. In the meantime, you need to bring a hat and sunglasses to keep out the sun. It's cooler in the north and chilly at night, so be sure to bring a thick coat.
