Burning Season in Thailand
Worse Than Too Much Rain - Northern Thailand
Most travelers concerned about weather in Thailand ask about the rainy season. Those who are planning to travel to islands in the Gulf of Thailand or the Andaman Sea wonder about the monsoons
Unless you have visited Northern Thailand during the burning season you may not think that burning a little rice-straw is a big problem.But is certainly can ruin a holiday!
Burning in Northern Thailand, Burma, Laos, Cambodia and Southern China is an annual problem and seems to be getting worse.
What to Expect
