Thailand in the rainy season

On the west coast of Thailand, the Andaman Sea, the monsoon rains are between May and October and swimming in the sea at this time can be hazardous, look out for warnings against bathing. This can be a good time for trekking in the north, although some tails may be muddy and difficult. This is not a bad time for travelling in Thailand, it is not too hot and the showers do not last for too long.

Thailand has two distinct climates:  tropical savanna climate in the northern part of the country and a tropical monsoon climate in the south and southeast. There are three seasons: the so-called "cool" season (November to February) with day-time temperatures between 21 and 30 degrees, the hot season (March to the end of May) with average temperatures around 38-40° C degrees and the rainy season (June to October) in which sunshine alternates with short, heavy rain showers.

Summer is from late March to the end of May. At this time begins a heat can make travelling, especially in Bangkok, somewhat tiring.  Sultry temperatures up to 40° C and high humidity mean you must take it a bit easy. It is mostly dry however and cooler weather can be found in higher mountainous regions and at our famous seaside resorts.
