Travel insurance
This destination does not require insurance to enter, according to the official source. It is still worth having: abroad, a doctor visit or an evacuation comes out of your own pocket.

What else you may be asked for on entry
Besides your passport. Each one with the official wording behind it.
Proof of onward travelyou may be asked
Thai immigration officials or airline staff may ask for your onward/return ticket or financial ability to remain in Thailand.
Only the US (State Department) mentions it. The UK source does not.
Sufficient fundsyou may be asked
Thai immigration officials or airline staff may ask for your onward/return ticket or financial ability to remain in Thailand.
Only the US (State Department) mentions it. The UK source does not.
Official travel advice from the UK (FCDO) and the US (State Department). Each source is written for ITS OWN nationality, not yours: a duty may not apply to you, and one that neither source mentions may.
Check your own dates
The rule is one thing; whether your passport clears it on your travel dates is another. Turkey counts 150 days, not five months. Costa Rica counts one day. Schengen countries check two rules at once.

What happens if you do not meet it
Airlines check validity at check-in and can refuse to board you — they face fines of 3,500 to 10,000 US dollars for carrying a passenger who is then refused entry. One denied boarding costs the traveller between 1,200 and 2,400 US dollars in lost fares, hotels and rebooking. In 2025, 1.2 million people were denied boarding or entry over passport problems, and 40% of those were validity.
Source, word for word
To enter Thailand, your passport must have an 'expiry date' at least 6 months after the date you arrive and have at least 1 blank page. Check with your travel provider that your passport and other travel documents meet requirements. Renew your passport if you need to. You will be denied entry if you do not have a valid travel document or try to use a passport that has been reported lost or stolen.
