Thailand's hot season will officially begin on February 28

According to Thailand's Meteorological Department, the hot and dry season will officially begin on February 28 and last until mid-May.

Dr. Sugunyanee Yavinchan, director general of the department, said the average maximum temperatures are expected to be 35 to 36°C, which is slightly lower than last year.

These forecasts are much less alarming than those announced on February 11.

The determination of the transition from the cool season to the warm season is based on the fact that:

• The maximum temperature in more than 60% of northern, northeastern, central and eastern parts of Thailand is continuously above 35°C;
• The northeast monsoon wind across northern Thailand changes to a southeast flow.

April will be the hottest month, with temperatures exceeding 42°C in 14 provinces, including Mae Hong Son, Tak, Chiang Mai, Lamphun, Lampang, Uttaradit, Sukhothai, Phitsanuloke, Loei, Nong Khai, Udon Thani, Nong Bua Lamphu, Khon Kaen and Chaiyaphum.

Occasional storms are also expected.

Rainfall during the dry season will be up to 20 percent higher than last year, but it will not be widespread or sustained, Dr. Sugunyanee said.

A new moderate to strong cold front is expected to cover northeastern Thailand and the South China Sea from Sunday, February 23 to Tuesday, February 25.

This could lead to heavy rainfall.
