As such, you can expect large crowds at popular attractions. To ensure that your trip goes smoothly, it is wise to plan and book activities and accommodation in advance.
In terms of cost, Thailand remains a relatively affordable destination. However, during the high season, prices for accommodation, flights and entertainment can be higher due to increased demand.

What to wear in Thailand in January?
The weather in Thailand in January is pleasant and dry. To feel comfortable, bring lightweight, breathable clothing such as shorts, t-shirts and sundresses for warm daytime temperatures and don't forget swimwear for beach holidays.
Despite the warm days, evenings can sometimes be chilly, especially in northern regions, so bring a light jacket or long-sleeved shirt just in case. It is absolutely essential to take sunglasses, hats and sunscreen for sun protection.
Apart from this, modest clothing covering shoulders and knees is recommended for temple visits. Also, some southern areas may experience occasional rain, so a small umbrella or mackintosh is not unreasonable.
