A Complete Guide to Thailand’s Weather

Written by Danielle Gunner Last updated November 2nd 201702/11/17

Typically the summer monsoon season in Thailand runs from June right through to October, but the unpredictable nature of the weather in the area does mean that some parts of the country aren’t hit as badly as others.

The hottest months come just before the summer really kicks in, so visiting Thailand in British summertime will mean fantastic low-season deals. This beloved holiday destination has received some fantastic positive attention for its vibrant beach culture and relaxed island hopping days at sea, so bagging yourself a bargain is highly recommended.

Thailand, especially during the monsoon season, hammers down intensely for an hour or less before clearing away again, meaning that even in the wet season, it’s not as big a deal as you might think.

The highest rainfall tends to occur in September, although you’ll find that by and large, Thailand’s monsoon season commences properly in late June running through to early October.

Location, location, location

Another factor to consider is where in Thailand you’re planning to holiday. It’s a big place, after all, which means the weather here can be extremely diverse.

On the Anderman Sea, Phuket, Krabi, Khao Lak and the western Isthmu region, the rain can start much earlier which means it also clears up sooner, so if you’re lucky you may just catch a warm week here or there in August or early September.

Don’t fret though, as Thailand is just as beautiful in the wet as it is in the dry. You’ll also benefit from low tourist traffic at this time of year, which means a more authentic experience.

So when you do go visiting those ruins, temples or beaches you’ve had your eye on, there are far less crowds to contend with. Waterfalls will be rushing, rivers will be ripe for rafting and low-level ruins will become a great diving activity.

Summer temperatures

Whichever month you visit Thailand though, high temperatures and sumptuous beach weather are a given. Thermometers reading well above 30°C are the norm all year round, although especially so in March, April and May.

The traditional British summer months, even if you’re taking advantage of monsoon season price drops, also see their fair share of hot days, hovering in the high 20s to low 30s day in, day out.

That means your Thailand holiday will offer plenty of heat and humidity, so pack accordingly and ensure that you’ve got your camera ready for the sights.
