The Complete Thailand Packing List

From Bangkok temples to Phuket beaches, everything you need for a tropical trip that respects local culture.

Updated April 13, 2026

Quick answer

Pack lightweight breathable clothing, temple-appropriate cover-ups for shoulders and knees, reef-safe sunscreen, strong insect repellent, and a universal plug adapter rated for 220V. Bring quick-dry footwear, a rain jacket if visiting May through October, and loose cotton for Bangkok's 95F humidity. US citizens get 60 days visa-free on arrival. Cash is still widely needed outside Bangkok.

Thailand is hot, humid, and far more conservative than its beach photos suggest. The sweet spot is breathable, lightweight, and modest enough for temples. A sarong or light scarf is one of the most versatile items you can pack: it doubles as a temple cover-up, a beach mat, a sun shade on long-tail boats, and a blanket on chilly overnight buses.

Power runs on 220V at 50Hz with a mix of Type A, B, and C sockets depending on the building. Most newer hotels have hybrid outlets that accept US plugs directly, but a universal adapter is still worth carrying. Any device you plug in must be rated for 220V (check the fine print on the charger) or you will fry it. Almost all modern phone, laptop, and camera chargers handle 100-240V fine.

Mosquito-borne disease is the single health concern worth planning for. Dengue is endemic year-round and spikes in rainy season, and malaria exists in rural border areas. DEET or picaridin repellent, long sleeves at dusk, and accommodations with screened windows are the baseline defense. Reef-safe sunscreen is legally required at many marine national parks including Koh Tachai and the Similan Islands. Pack it from home; the selection locally is thin.

Visa

As of July 2024, US citizens can enter Thailand visa-free for up to 60 days for tourism, doubled from the previous 30 days. The stay can be extended once for 30 additional days at an immigration office. You need a passport valid 6 months beyond your entry date and proof of onward travel. The Thailand Pass and all COVID-era requirements have been dropped.

SIM / data

Buy a DTAC, AIS, or TrueMove tourist SIM at the airport arrival hall for around 300 baht. Data is cheap and coverage is excellent in cities and most tourist areas. eSIM options like Airalo work on all major carriers. WiFi is widely available at cafes, hotels, and 7-Elevens.

Tipping

Tipping is appreciated but not obligatory. Leave 20-50 baht at sit-down restaurants if no service charge was added. Round up taxi fares and leave 50-100 baht for bellhops and housekeeping. Thai massage (traditional) often warrants a 50-100 baht tip for a quality hour. Street food and casual meals do not require tips.

Cultural notes and dress codes

  • Cover shoulders and knees when entering temples (wats). Many major temples including the Grand Palace will refuse entry or require you to rent a cover-up. Loose pants or a long skirt plus a shirt with sleeves is the safe default.
  • Remove shoes before entering temples, homes, and some shops. Watch for piles of shoes at the entrance as your cue.
  • Never touch someone on the head, even playfully. The head is considered the most sacred part of the body.
  • Do not point your feet at people or at Buddha images. When sitting on temple floors, tuck your feet behind you.
  • The king and royal family are legally protected from any criticism under lese-majeste laws. Do not joke about or criticize them even in private conversation with locals.
  • Public displays of affection beyond handholding are frowned upon, especially outside Bangkok and tourist beaches.
  • The wai (palms pressed together, slight bow) is the traditional greeting. A returned wai with a smile is always appreciated.
  • Women must not touch Buddhist monks or hand objects directly to them. Place items on a surface or cloth for the monk to pick up.

When to visit and what changes by season

Cool Dry Season (Peak Tourism)

November, December, January, February · 75-88F with lower humidity, cooler in the north (Chiang Mai nights drop to 55F)°F

The driest, most comfortable stretch and the peak tourist window. Andaman and Gulf seas are both calm December to February. Chiang Mai gets smoky from agricultural burning late February to early April.

  • Light layers for chilly northern mornings
  • Standard tropical lightweight clothing
  • Reliable sunscreen for full beach days
  • Light long-sleeve for evenings in the north
  • Reef-safe sunscreen for island trips

Hot Dry Season

March, April, May · 85-100F with punishing humidity, especially in Bangkok°F

The hottest months. Songkran (Thai New Year, April 13-15) brings massive public water fights in Chiang Mai and Bangkok. Burning season haze peaks in Chiang Mai March and early April.

  • Waterproof phone case and dry bag for Songkran
  • Swimwear-layer friendly outfits for water festival days
  • N95 mask if visiting Chiang Mai in burning season
  • Cooling towels and maximum-breathability fabrics
  • Electrolyte tablets

Rainy Season (Andaman and Central)

June, July, August, September, October · 78-92F with heavy rain and high humidity°F

Daily afternoon thunderstorms rather than all-day rain. Andaman islands see rough seas, some closures (Similan closed mid-May to mid-October), cheaper prices, and lush green landscapes. Gulf coast (Koh Samui) is still relatively dry.

  • Quality rain jacket or compact travel umbrella
  • Quick-dry footwear (sneakers stay wet for days)
  • Waterproof backpack cover
  • Extra dry bags
  • Indoor activity research for heavy rain afternoons

Rainy Season (Gulf Coast)

October, November, December · 78-88F with heavy rain especially November°F

Koh Samui, Koh Phangan, and Koh Tao get their wet window now. November is the peak rain month. December storms can delay ferries. Andaman side is already drying out.

  • Rain jacket and dry bag
  • Flexible bookings in case of ferry cancellations
  • Waterproof phone pouch
  • Warmer layer for rainy evenings (75F feels chilly after beach days)
  • Digital copies of bookings in case of power outages

Packing tips for Thailand

  1. 1 Use metered taxis in Bangkok (say mee-ter or the driver will quote a flat fare) or stick to Grab, which covers Bangkok, Phuket, Chiang Mai, and most major cities.
  2. 2 Carry small bills. Vendors, tuk-tuks, and street food stalls struggle to break a 1,000 baht note. Break large notes at 7-Eleven or convenience stores.
  3. 3 Drink only bottled or filtered water. Ice at reputable restaurants is fine (made from purified water) but ice at street stalls is a coin flip.
  4. 4 Download Grab, Klook, Line, and offline Google Maps before you arrive. Line is the default messenger and many businesses only take Line bookings.
  5. 5 Negotiate politely at markets (Chatuchak, night bazaars) with a smile. Start at 50-60 percent of the asking price and meet in the middle. Do not haggle over prices under 100 baht.
  6. 6 Book train tickets on 12Go or the official Thai Railway site for longer routes. The overnight train Bangkok to Chiang Mai is a classic and saves a hotel night.
  7. 7 Bring a copy of your passport to carry day-to-day and leave the original in the hotel safe. Police can ask for ID checks.
  8. 8 Avoid elephant rides and tiger parks. Ethical elephant sanctuaries (no riding, observation only) are the responsible alternative.

Frequently asked questions

Do I need a visa to visit Thailand?
US citizens do not need a visa for tourist stays up to 60 days, after Thailand doubled the visa-exempt period in July 2024. You need a passport valid at least 6 months beyond entry and proof of onward travel. You can extend once for an additional 30 days at a local immigration office. Longer stays require a proper tourist visa (TR) applied for in advance at a Thai consulate.
What plug type does Thailand use?
Thailand uses Type A, B, C, and O outlets at 220V, 50Hz. Many newer hotels have hybrid sockets that accept US two-prong plugs directly, but an older guesthouse may only fit Type C (European round). A universal travel adapter covers everything. Any device you plug in must be rated 100-240V, which almost all modern phone and laptop chargers are. High-wattage US appliances like hair dryers will burn out.
What should women wear in Thailand?
Outside beaches and tourist areas, cover shoulders and knees. At temples, this is strictly enforced; at markets and city streets it is a matter of respect and fewer stares. Lightweight loose pants, midi skirts, and short-sleeve tops work everywhere. A sarong or light scarf is a go-anywhere cover-up. Beach towns like Phuket and Koh Samui are relaxed, but nothing beach-wear worthy of a temple visit.
Is Thailand safe for solo female travelers?
Yes, Thailand is one of the most solo-friendly destinations in Asia. Violent crime against tourists is rare. Common-sense precautions apply: avoid unmetered taxis at night, do not leave drinks unattended, and be cautious on rented scooters (the top cause of tourist injury). Petty theft exists in nightlife areas. Most solo travelers report feeling very safe throughout the country.
Can I drink tap water in Thailand?
No. Stick to bottled or filtered water even for brushing teeth in some areas. Ice at reputable restaurants, hotels, and chain cafes is made from purified water and is fine. Ice from street carts and remote rural vendors is a coin flip. Bring a filter bottle like Grayl or LifeStraw if you want to cut plastic waste.
What is Songkran and how do I pack for it?
Songkran is the Thai New Year, celebrated April 13-15, and it has turned into the world's biggest water fight. If you are in Chiang Mai, Bangkok, or Phuket during those days, expect to be soaked whenever you step outside. Pack a waterproof phone case or pouch, quick-dry clothes, a dry bag for your wallet and passport, and shoes you do not mind soaking. Most travelers embrace it; it is spectacular.
Do I need vaccinations for Thailand?
Standard routine vaccines plus Hepatitis A and typhoid are the CDC's baseline recommendations. Hepatitis B, Japanese Encephalitis (for rural long-stay), and rabies are worth discussing with a travel doctor. Malaria pills are usually unnecessary for standard tourist routes but may be recommended for remote forested border areas. Dengue has no vaccine for most travelers, so bite prevention is the only defense.
Is reef-safe sunscreen required in Thailand?
Yes, at marine national parks. Since 2021, Thailand has banned sunscreens containing oxybenzone, octinoxate, 4-methylbenzylidene camphor, and butylparaben at national marine parks including the Similan and Surin Islands. Rangers do check. Buy mineral-based zinc or titanium dioxide sunscreen from home; the local selection is limited and expensive.
How much cash should I bring to Thailand?
Card acceptance is good in Bangkok hotels, malls, and nicer restaurants but spotty everywhere else. Plan to carry 2,000 to 3,000 baht (about 55-85 USD) in cash per day. ATMs are everywhere but charge a 220 baht foreign transaction fee per withdrawal, so pull out larger amounts at once. Use a Charles Schwab or Fidelity debit card to avoid the fee.
What is the best time to visit Thailand?
November through February is the cool, dry, peak season with the best weather nationwide. December and early January are the most crowded and expensive. March to May is punishingly hot but has the best beach prices. June to October is Andaman rainy season (Phuket, Krabi) but still fine on the Gulf coast (Koh Samui). For Chiang Mai, avoid March and early April due to burning season haze.
