Thailand’s Climate & Weather is influenced by monsoons that sweep over the country creating three seasons in the north and central areas and two in the south.
Hot Season – boasts high temperatures and lightweight cotton clothes are best.
Cool Season – a few warmer layers are required as temperatures drop at night.
Rainy Season – sees heavy rainfall throughout due to the effects of the southwest monsoon.
Hot Season -high temperatures/humidity.
Cool Season – remains quite hot but evenings tend to be cooler and a few warm layers are required.
Rainy season – most rain tends to fall between August and September – flooding can be common towards the end of this period.
Differences in temperature and rainfall occur during both seasons on the east and west coasts.
Rainy Season – torrential rain tends to fall in short bursts, usually lasting only a couple of hours each day. Most rain falls between June and November.
Hot and Dry Season – is relatively rain-free between January and April.
Flooding on the west coast is commonplace. Travel elsewhere during the rainy season is not necessarily problematic unless visiting areas where roads are unpaved, as rain renders these tracks impassable.
Carry a lightweight jumper as it can be chillingly cold inside air-conditioned buildings.
The climate of Northern Thailand is slightly more pleasant than other parts of the country.
Light cotton clothes are recommended all year round.
Hot Season – high temperatures are experienced throughout the day and only drop slightly at night.
Rainy Season – heavy rainfall throughout, although temperatures remain quite high. An umbrella is always useful at this time as it is sometimes too warm to consider wearing waterproof clothing.
Cool Season – warmer clothes are required during the cooler months when temperatures fall slightly through the day and even more so at night. Very little rain falls during this time.
High humidity is prevalent throughout the year, except in the more mountainous regions.
