Is it hot to travel to Thailand in May?

It's hot, but it's passable. May has entered the rainy season, and it may rain at any time. Remember to bring an umbrella. Rain comes and goes quickly. If the temperature is 30 degrees, it will be sultry and humid when it doesn't rain, and it will feel a little sticky, just like summer in southern China.

Wear long sleeves, because the air conditioner is too full in many places and it will be cold. Remember to bring a raincoat or umbrella.
