Weather plays an important part in our travel experience. It is uncomfortable if the temperature is too hot or too cold. Rain and thunderstorm can ruin your whole travel plans. This is why it is important to check the weather before deciding on a destination at a particular time. Thailand is a tropical country, and the temperature doesn’t vary much in central and southern Thailand. The north, however, is more affected by the monsoon. The average temperatures are usually somewhere between 18°C to 35°C. The seasons can be classified into 3 major ones:

  • Hot Season: March to June
  • Rainy Season: June to October (this can vary)
  • Cool Season: November to February

Hot season

This is perhaps one of the worst months to visit Thailand if you can’t tolerate the scorching heat. Temperatures in Bangkok average 30°C, and can reach up to 40°C during this time. In addition to being very hot, it is also very humid and makes sightseeing an uncomfortable experience. Visiting temples and going anywhere without air conditioning without being dripping wet from all the sweat.

Luckily, Bangkok has a very good and cheap transportation system with AC, and taxis are cheap. And there are plenty of indoor activities such as shopping, restaurants, and movies. And if you can still have a great time in Bangkok during this season without stepping out in the sun. Also, the islands are also another good idea during this time. You can take a dip in the sea, which can cool off some heat.

In reality, Thailand is pretty hot the whole year in general. An exception might be the Northern areas during the cool season. There are some benefits to the hot season as well. There is less rainfall, and you will not need to cancel any travel plans for the rain or flood. Tips for traveling during this time are drinking plenty of water and liquid, being under the shade, and AC whenever you can, loading up on sunscreen, and carrying a small portable fan.

Rainy Season

The rainy season which typically starts during June and runs through October is when the country has the most rain. However, the good thing is it doesn’t mean it will constantly rain even during this time. It can rain for days at a time, and there have been instances when it hasn’t rained for days or weeks. Another advantage of this season is that hotel prices are generally much lower.

But it can be a gamble. If you’re lucky you can do plenty of sight-seeing with some rain during the evenings, or you can be stuck in your hotel due to heavy rain. The destination on the Andaman seaboard such as Krabi and Phuket, the rainy season officially runs from May through October. On the gulf coast, however, it starts much later.

On the islands of the gulf coast such as Koh Samui and Koh Phangan, much of the rainfall occurs from September to December. Which is why if you’re visiting Thailand from June to August, and craving some vitamin sea, Koh Samui and Koh Phangan can be great options. But keep in mind, nature doesn’t follow strict timetables. So there might be exceptions to this as well.

Also, one thing to keep in mind is that there is a risk of flash flooding during the monsoon. This can occur in both big cities and the islands. However, if you’re lucky and the weather is by your side, you can have a great holiday at a bargain price.

Cool Season

If you’re wondering what is the best time to visit Thailand, it is during November/ late October to February. While it will still be hot, it will be quite comfortable than the rest of the year for most activities during this time. In Bangkok and some other places, temperatures can go up to 30°C. But if you’re heading towards the northern highlands such as Chiang Mai and Chiang Rai, the weather can get chilly.

So be sure to carry a light sweater/ jacket. Chiang Mai and Chiang Rai are undoubtedly very beautiful during this time of the year, you can enjoy gorgeous views of mountains covered in cool mist. Krabi and Phuket are also great during this time. While the sun is still up and shining, the heat is bearable. This is also the peak time for traveling in Thailand. This means you will have to pay a little extra to visit the land of smiles during this time. However, it is worth the extra money without a doubt.

Festival calendar

Thailand is a beautiful country with a lot of diverse and unique cultural experiences. And although weather plays a major role in deciding when you want to visit a certain country, you can also narrow down your most preferred time by looking at the festivals and celebrations that happen throughout the year.
