History
[edit]
The territory of Mae Hong Son Province was formerly part of Mawkmai State, one of the Shan States which had been founded in 1767 by Hsai Khiao, hailing from a noble family of Chiang Mai.
As a result of the Anglo-Siamese Boundary Commission of 1892-93 Mae Hong Son district was ceded to Siam, but the adjacent Möngmaü and Mehsakun trans-Salween districts— also claimed by Siam as territories located on the eastern side of the Salween River— were kept as part of British Burma.
Climate
[edit]
Mae Hong Son has a tropical savanna climate (Köppen climate classification Aw). Winters are dry and warm. Temperatures rise until April, which is very hot with the average daily maximum at 38.7 °C (101.7 °F). The monsoon season runs from May through October, with heavy rain and somewhat cooler temperatures during the day, although nights remain warm. Mae Hong Son holds the highest temperature ever recorded in Thailand when 44.6 °C (112.3 °F) was observed on 28 April 2016.
