The best time to go to Thailand really depends on what you're looking for from your holiday. Thailand is a year-round destination, so there's never a bad time to visit!
If you're looking for Thailand's peak season with the best weather and most tourist activities, then plan your trip between November and early April. These are Thailand's dry months, with little rainfall and temperatures averaging 27-30°C degrees.
However, Thailand's rainy season between July and October can also be a great time to visit. The prices are lower, there are fewer tourists and you can often find some great deals on accommodation and activities. Just be prepared for the odd heavy downpour!
No matter when you choose to visit Thailand, you're sure to have an amazing holiday!
