Thailand safety: the real risks on roads, beaches and in the heat

Thailand is safe for most visitors, and nearly everything that sends people to hospital is predictable. Roads come first by a distance. Then come the sea, the heat, bad drinks and animal bites. Plan for those five first.

This guide is for first-timers and for anyone staying more than a fortnight. Skip it if scams are all you need: the scams guide covers those in depth.

Save the numbers first

Put these in your phone before you land. The In an emergency page has hospitals and a printable sheet.

The catch: English on 191, 1669 and 199 varies. If you struggle, call 1155 or ask a Thai speaker nearby to ring for you.

Before you fly: insurance and mosquitoes

Buy travel insurance that covers hospital stays and evacuation, and read the exclusions for scooters and alcohol. Thailand’s private hospitals are excellent, and their bills run high without cover. The healthcare and insurance guide compares what policies pay.

Dengue is present across Thailand. Ask a travel clinic about prevention, and rely on repellent. Transmission peaks in the rainy season but continues all year. The mosquitoes that carry it bite in the daytime, so wear repellent with DEET on skin and long, loose clothes at dawn and dusk, and sleep in a screened or air-conditioned room.

Malaria is a regional issue. The CDC places it in rural, forested border areas (with Myanmar, Cambodia and Malaysia), and describes Bangkok, Phuket and the main tourist islands as low to negligible risk. If your route crosses those areas, see a travel clinic first.

Fever with a pounding headache, aching joints or a rash needs a doctor the same day.

The road is the real danger

Motorbikes and scooters cause most road deaths in Thailand. Both the CDC and the WHO say so, and the CDC advises visitors to avoid riding motorbikes, motorbike taxis included. A taxi or the BTS is safer. If you ride anyway:

• Hold the right licence. You need a licence valid in Thailand for motorcycles. A car-only licence will not do. The driving licence guide explains the International Driving Permit and what insurers refuse to pay.
• Wear a helmet, rider and passenger. Since filming: from 1 June 2025 police began enforcing the helmet rule for riders and passengers, with fines of up to 2,000 baht.
• Avoid the holiday peaks. New Year and Songkran in mid-April are the worst travel periods on Thai roads.
• Remember the left. Traffic drives on the left. Never learn to ride in Bangkok, and don’t rent a bike you can’t handle.

Ask any rental shop for the bike’s registration and insurance before you sign. Tourist-area rental bikes are often unregistered, and your own policy may refuse a claim on one.

Crossing the road

Don’t expect cars to stop at a zebra crossing. Many drivers treat them as decoration, and motorbikes may run red lights or ride against the traffic.

Use a footbridge or a signalled crossing with a crowd. Look right first, then left, then right again. Make eye contact with the driver, and cross when the vehicle has actually stopped, not when it has slowed.

In the sea

Thai beaches have two real hazards: box jellyfish and rip currents. Sea urchins are a nuisance and sharks are rare.

Jellyfish

The Tourism Authority says box jellyfish are mostly a risk in the south, and stings are most likely in the rainy season. They are hard to see. Swim only where nets or lifeguards are in place, and stay out wherever a warning sign is posted.

If you are stung:

1. Get out of the water and call 1669.
2. Pour vinegar over the area for at least 30 seconds.
3. Don’t rinse with fresh water, scrub, or apply sun cream; the Tourism Authority says these make the sting worse.
4. Keep the person still and go to hospital. Stings from larger jellyfish can be life-threatening.

Rip currents and red flags

The Andaman coast, including Phuket, is rough from roughly May to October. Lifeguards fly red flags where rip currents are likely. Treat a red flag as a closed beach.

If a rip pulls you out:

• Don’t swim against it. Float or tread water to save your strength.
• Swim sideways, parallel to the shore, until you leave the current, then angle back in.
• Wave and shout if you can’t break free.
• Don’t swim at night or after drinking.

Sea urchins

Black urchins sit in rocky shallows and on reefs. Their spines break off in the skin and can inflame or infect it. Wear water shoes on rocks, and don’t touch the bottom while snorkelling. If you get spines in your foot, soak it in comfortably hot water and have a clinic remove what it can. Ask about tetanus.

Animals

Dogs, cats and monkeys

Street dogs are common in every city and mostly ignore you. Don’t pet them, and don’t run if one threatens you. Stand still, face it and back away slowly until you are out of its patch.

Macaques live around temples and in coastal and island towns. They snatch phones, bags and food. Keep food out of sight, hold valuables in front of you, and don’t feed them.

A bite or scratch from any animal needs the same response.

• Wash the wound with soap and running water for at least 15 minutes, per WHO guidance.
• Apply an antiseptic such as povidone-iodine.
• Go to a hospital or clinic the same day. Hospitals and clinics can give the rabies vaccine and immunoglobulin. Start the course at once and don’t wait to see whether the animal falls sick.

The CDC does not recommend rabies shots before you travel unless you work with animals or will be far from medical care.

Snakes

Most Thai snakes avoid people. Bites happen in long grass, in gardens and after heavy rain, when snakes move. Wear closed shoes and use a torch at night.

If you are bitten, keep still, keep the limb level with your body and get to a hospital quickly. Don’t try herbal or folk remedies. Note the time, and photograph the snake from a safe distance only if it costs you no time. Thai hospitals use antivenoms made for local species, and knowing which snake you met helps them choose.

Food and water

Street food

Choose stalls where food is cooked to order and served hot, where there is a queue, and where you can see clean dishes and running water. The CDC names street food as a common source of traveller’s diarrhoea and recommends skipping raw items.

Cut fruit and smoothies are the weakest links: they are raw, and made with water and ice you can’t check. Peel your own fruit if you are unsure.

If you get food poisoning, drink fluids and rest. See a doctor for fever, blood in the stool or symptoms that last.

Water

Drink bottled or filtered water everywhere. Bangkok’s water authority says its supply meets drinking standards when it leaves the treatment plants, but the CDC advises visitors not to drink tap water, and old pipes and building tanks can add contamination on the way to your tap.

Use bottled water for drinking and brushing teeth. Ice in busy restaurants is usually made from filtered water; skip it on islands and in rural areas if you want to play it safe.

Heat

The hottest weeks come before the rains, and a first visit from a cooler country can hit hard. Heat exhaustion catches many first-time visitors, so plan lighter days.

• Do temples, markets and walks early, then spend the afternoon indoors.
• Drink water before you are thirsty, and carry a bottle.
• Wear a hat and light, loose clothes, and rest in shade or air conditioning.
• Skip alcohol while you’re outside.

Heat stroke is an emergency. Confusion, fainting, hot skin and a fast pulse are the signs. Call 1669, move the person into shade or air conditioning, and cool them with wet cloths, fanning and water.

The cooler months from about November are kinder if you are heat-sensitive.

Drinks: fake alcohol and spiking

Methanol-contaminated spirits have caused deaths and serious illness in Thailand. You cannot detect methanol by taste or smell. The Australian and UK governments both advise drinking only branded drinks from sealed bottles and cans, and treating spirit buckets, jugs and free shots with caution.

Never accept a drink from a stranger or leave yours unattended, and don’t go back to a drink you lost sight of. If you feel suddenly drunk, dizzy or unwell, tell a friend and the venue staff, and go to a hospital.

Use a ride-hailing app rather than a street taxi when you leave late. In the app, check that the plate and driver match before you get in, and share your trip with a friend.

Petty crime and arguments

Pickpocketing and bag-snatching from passing motorbikes are the usual street crimes. Carry your bag on the side away from the road, keep phones out of back pockets, and don’t leave a phone on a café table beside the pavement.

Leave one spare bank card at your accommodation. ATMs here take most foreign cards, so a backup keeps you in cash.

Fights are rare, but a raised voice, a drunken insult or a row over a bill can pull in bystanders. If you are overcharged, don’t argue. Walk away and call the Tourist Police on 1155.

Theft or a scam: call 1155, then your bank to freeze any card.

Fake job offers

Fraud rings in neighbouring countries recruit foreigners with offers of well-paid online work, then take their passports and hold them in compounds across the border. The UK government and the UN both warn of this.

Treat any job offer that asks you to travel to Thailand, or onward across a border, with suspicion. Check the company yourself, and never hand over your passport. Never cross a border on a recruiter’s instructions. If something feels wrong, contact your embassy. The scams guide covers fake rentals and job-fee scams.

Thai law and what you post

You are subject to Thai law the moment you land. Defamation is the one that catches visitors. The US, UK and Australian governments warn that a critical post, a negative online review or a comment about a named person or business can bring criminal charges, even when you think it is true.

Keep reviews factual, and keep arguments off social media.

Regional advice

Most governments advise against travel to Yala, Pattani and Narathiwat. Check your own government’s advice for those provinces and the border areas the week you fly.
