Thailand enters winter on 9 Nov with Northeast to cool 3–5°C

Residents and farmers are urged to prepare for cooler weather, with temperatures in Bangkok and surrounding areas forecast to fall by 1–3°C.

  • Thailand's winter season officially began on November 9, according to the Thai Meteorological Department.
  • The cooler weather is caused by a strong cold air mass from China moving over upper Thailand.
  • The Northeast region is forecast to experience the largest temperature drop, with a decrease of 3–5°C.
  • Other regions, including the North, Central, East, and Bangkok, are expected to see a smaller temperature drop of 1–3°C.

The Thai Meteorological Department (TMD) has announced that Thailand officially entered winter on Monday (November 9) with cooler weather and strong winds expected across upper Thailand. Temperatures in the Northeast are forecast to fall by 3–5°C.

The TMD attributed the cooler conditions to a relatively strong cold air mass from China spreading over upper Thailand and the South China Sea. The system is also strengthening easterly winds across Thailand and the Gulf of Thailand.

Northeast forecast to see largest temperature drop

The TMD forecasts a temperature decline of 3–5°C in the Northeast, the largest drop among the regions covered by the outlook.
