The Thai race was previously believed to have originated somewhere near Mongolia, later moving southward. However, new theories based on historical discoveries regard the northeastern part of Thailand as the birthplace of the Thai race. Over the years, the country has become home to many immigrants. The Thai people have managed to preserve the traditions of their unique culture, at the same time absorbing the practices of modern living. Nevertheless, the combination of cultures and backgrounds of these immigrants make Thailand an interesting and memorable country to visit.
Summer monsoons begin as the warm humid air masses flow towards the north from the Indian Ocean.
The monsoons end in the fall when the wind reverses direction with the dry southwesterlies. The amount of rainfall varies with topography. The northeast receives the least rain, while the south is flooded during the summer months. The best time to visit Thailand is during the cool season, from October though February, when it is not as humid as during the summer and rainy seasons. The people of Thailand share a rich ethnic diversity consisting of Thai, Mon, Khmer, Laotian, Chinese, Malay, Persian and Indian descendants.
