New Year weather around Thailand

It might be the middle of the annual high season but the ‘high season’ weather isn’t co-operating. Although generally fine weather has been the trend in the past few days there are a few unseasonal fronts coming to different parts of the country, according to the Thai Meteorological Department.

In the central/southern provinces, including around Hua Hun and Gulf islands of Samui, Koh Phangan and Koh Tao, it will less of the Christmas ho-ho-ho and more of the New Year ho-hum. A weakening tropical depression is going to drop some rain in those regions as the week develops.

According to the TMD, a strong high-pressure system covers the upper Thailand and remains dominant until January 2, 2019 while the westerly trough moves into the northern regions.

From today until January 2, 2019: Cool to cold spells with strong winds. In the north and the north-east temperatures decrease by 5-8 °C while on the mountaintops get cold to very cold with lowest temperatures of 3-13 °C.

In the central and eastern regions, Bangkok and vicinity regions temperatures decrease by 3-5 °C.

The south will get more rains with some heavy downpours affecting first Phetchaburi and Prachuap Khiri Khan, then the rest of the southern provinces.

People should be aware of the severe conditions. In the Gulf of Thailand, there will be strong wind, waves 2-3 metres high. All ships should proceed with caution, and small boats in the Gulf keep ashore lasting January 2, 2019.
