Thailand travel preparation guide

What to check before departure

Prepare according to city and season

Pack lightly for hot seasons

Hot seasons are generally February–April in central and northeastern regions and March–April in the north. Focus on light clothes and a hat.

Check each island’s coasts separately

The north and central regions generally have a rainy season from May–October. Seasonal patterns differ between the southern Andaman Sea and Gulf of Thailand, so check the weather by island name.

When checking voltage

Sockets accepting flat two-pin, round two-pin, and three-pin plugs coexist. Check your accommodation’s specifications.

Start step by step with documents and reservations

Check visa conditions on Thailand’s Ministry of Foreign Affairs e-Visa site and arrival-card procedures in the immigration authority’s TDAC guidance.

Prepare your passport and reservations, and check entry conditions for your travel purpose, passport type, stay duration, and transit route. Note when you checked official guidance and recheck for changes before departure.

Pack for your itinerary

Items needed in Thailand vary by city and season. Check your destination city’s forecast shortly before departure, and adjust clothing and everyday supplies to your accommodation’s amenities and laundry availability. You can add your own items to the common checklist.

Check official information

This is general preparation information, not confirmation of permission to enter. The latest official conditions take priority.
