May is the dry season and spring so bound to be hot. Its normally above 30 degrees however you dont want to be in thailand in the wet season which is between Nov and Feb......May is a great time to travel!

It really depends where in Thailand you plan on traveling to. Different parts of the country have different wet seasons. For example in the south west coast the season is typically Sept - Nov/Dec. However up north it is June - August.
