Cool weather and strong winds: Thai weather warning for today!

What's new in Thailand's weather? A fresh high pressure system from China has made its way and is now spreading over southern China and northern Vietnam. This mild high pressure area will reach northeastern Thailand today and soon expand across northern Thailand, according to both the Nation of Thailand and the Thai Meteorological Agency.

The coming days promise cooler temperatures and strong winds for the northeast. Thermometers predict a drop of 1 to 2 degrees Celsius, which is notable for this region. There could be denser fog in some areas, especially during the morning hours. Cool weather and morning fog can also be expected in the center and east of the country.

Changeable weather and health

Be prepared for changeable weather! Rain influenced by the easterly winds will occur in some regions of lower central and eastern Thailand. For the population, this means keeping a close eye on their health. The changes in the weather can have an impact on well-being and older people and those with chronic illnesses should be particularly careful.

But that's not all: additional precautionary measures are also required when traveling. The fog can severely reduce visibility, which is why all road users are urged to drive with particular caution. In addition, increased fire risks should be taken into account due to the dry conditions.

Prospects for the south

The south is not excluded: isolated thunderstorms are expected here, while the northeast monsoon over the Gulf of Thailand and the south is weak but increasingly gaining strength. Sailors should be particularly careful as waves in the lower Gulf of Thailand could rise to around 2 meters and even reach over 2 meters during thunderstorms.

In summary, we can look at a diverse weather situation in Thailand, with cooler weather in the north and thunderstorms in the south. Have your rain jackets and sweaters ready and pay attention to the weather updates! This information refers to the current forecasts from Nation Thailand and the Thai Meteorological Authority.
