Thailand Travel Info
Everything you need to know before you go — visas, best time to visit, flights, climate, and health tips.
Entry Visas to Thailand
Thailand offers a generous visa policy for most international travellers. Depending on your nationality, you may enter visa-free, on a visa exemption, or by obtaining a visa on arrival or e-Visa in advance.
Visa Exemption
Citizens of over 60 countries — including the UK, USA, Australia, most of the EU, Japan, and South Korea — can enter Thailand without a visa for up to 30 days (extendable to 60 days from 2024). Check the Thai Ministry of Foreign Affairs for the current list.
Visa on Arrival (VOA)
Nationals of certain countries can obtain a 15-day Visa on Arrival at major international airports including Suvarnabhumi (Bangkok), Phuket, and Chiang Mai. A fee of approximately THB 2,000 applies.
Thailand e-Visa
Travellers who require a visa in advance can apply for a Thailand e-Visa online before departure. Tourist visas (TR) allow a 60-day stay and can be extended once at a local immigration office.
Visa regulations change periodically. Always confirm the latest entry requirements with the Royal Thai Embassy or consulate in your country before travelling.

Bangkok & Central Thailand
The cool and dry season from November to February is the most comfortable time to visit Bangkok and the central plains. Temperatures range from 20–32°C with little rain, making it ideal for sightseeing, temples, and street food exploration.
Northern Thailand (Chiang Mai)
The north is best visited from November to February when the air is cool and clear — perfect for trekking, visiting hill tribes, and enjoying the famous Loy Krathong lantern festival. April brings the lively Songkran (Thai New Year) water festival.
Southern Islands (Phuket, Krabi, Koh Lanta)
The Andaman Coast's high season runs from November to April, with calm turquoise waters and sunny skies ideal for diving, snorkelling, and island-hopping. The Gulf Coast islands (Koh Samui, Koh Phangan, Koh Tao) are best from January to September.
Airlines Serving Thailand
Thailand is one of Southeast Asia's busiest aviation hubs, served by dozens of international airlines. Bangkok's Suvarnabhumi International Airport (BKK) is the main gateway, with Don Mueang (DMK) handling low-cost carriers. Phuket (HKT) and Chiang Mai (CNX) also have direct international connections.

Thailand has a tropical climate. Temperatures and rainfall vary by region and season.
Climate & Seasons
Thailand has a tropical climate dominated by monsoons, with three distinct seasons. The cool season (November to February) brings dry weather and temperatures of 18–30°C, making it the most popular time to travel. The hot season (March to May) sees temperatures climb to 35–40°C, particularly in the north. The rainy season (June to October) brings heavy but typically short afternoon showers — the country stays largely accessible, and prices are lower with fewer crowds. The southern peninsula has two coastlines that experience different monsoon patterns, so at least one side is always in good weather.
Health & Safety
Thailand has an excellent healthcare infrastructure, particularly in Bangkok, Chiang Mai, and Phuket. International-standard private hospitals are found in all major cities and popular tourist areas. Government hospitals provide more affordable care throughout the country. It is strongly recommended to take out comprehensive travel insurance before your trip.
- Drink bottled or purified water only — tap water is not safe for drinking.
- Apply sunscreen regularly, especially in coastal and outdoor areas where UV levels are very high.
- Use insect repellent in jungle, rural, and evening settings to guard against mosquito-borne illnesses.
- Carry any personal prescription medication with a doctor's letter; many medications are available over the counter in Thai pharmacies.
- Obtain travel insurance that covers medical evacuation — it is inexpensive and essential.
- In the event of an emergency, contact your country's embassy or consulate in Bangkok.
