Thailand has had a constitutional monarchy since 1932. Parliament is composed of 2 houses, The House of Representatives and the Senate. Both representatives and senators are elected by the people. A prime minister elected from among the representatives leads the government. The country is divided into 76 provinces. The Bangkok Metropolitan Administration comes under an elected governor. Appointed provincial governors administer the other 75 provinces (Changwat), which are divided into districts (Amphoe), sub-districts (Tambon) and villages (Mu Ban).

Thailand enjoys a tropical climate with three distinct seasons-hot and dry from February to May (average temperature 34 degrees Celsius and 75% humidity); rainy with plenty of sunshine from June to October (average day temperature 29 degrees Celsius and 87% humidity); and cool from November to January (temperatures range from 32 degrees Celsius to below 20 degrees Celsius with a drop in humidity).
Much lower temperatures are experienced in the North and Northeast during nighttime. The South has a tropical rainforest climate with temperatures averaging 28 degrees Celsius almost all year round.

Electricity:

The electric current is 220 volt AC (50 cycles) throughout the country. Many different types of plugs and sockets are in use. Travellers with electric shavers, hair dryers, tape recorders and other appliances should carry a plug adapter kit. The better hotels will make available 110-volt transformers.

Light, cool clothes are sensible and a jacket is needed for formal meetings and dining in top restaurants. Shorts (except knee length walking shorts), sleeveless shirts, tank tops and other beach-style attire are considered inappropriate dress when not actually at the beach or in a resort area.
