Packing List for Thailand

Climate & when you're going

Thailand has two seasons that actually matter for packing: dry season (November–April) and wet season (May–October). Dry season means heat and sunshine — easier to pack for, but still 30°C+. Wet season means daily afternoon rain, higher humidity, and occasionally serious flooding in low-lying areas — but it's also when crowds are thin and prices drop.

The rain in wet season is typically a downpour that lasts 1–2 hours in the afternoon, then clears. You're not in constant rain; you're in heat with a daily afternoon interruption. A light packable rain jacket handles it. A full poncho and waterproof pants is overkill unless you're on a boat or motorbike regularly.

If you're going to northern Thailand (Chiang Mai, Chiang Rai) between November and February, pack one layer for cooler evenings — it can drop to 15°C overnight in the hills. Everywhere else, year-round, your baseline is hot and humid with a brief rain window.

Stow pulls live weather for each leg of your itinerary. If you're going Bangkok → Chiang Mai → Koh Samui, the weather note for each stop will reflect what's actually forecast — not a generic Thailand climate summary.

Clothing

Pack light, pack fast-drying, and pack one temple-appropriate outfit. That covers 90% of what Thailand demands.

The core rotation — 5–7 days before laundry

• 4–5 lightweight t-shirts or casual tops (cotton feels comfortable but takes forever to dry; linen or moisture-wicking synthetic dries in 2–3 hours and is worth it in Thailand's heat)
• 2 pairs of shorts or lightweight pants (shorts for most situations; pants for temples, nicer restaurants, and cooler northern evenings)
• 1 pair of lightweight long pants or a skirt (dedicated temple item — you'll use it at Wat Pho, Doi Suthep, and virtually every major temple; linen pants pack flat and work in the heat)
• 1 lightweight long-sleeved shirt or scarf (doubles as temple shoulder cover and sun protection on boat days)
• 5–7 pairs of underwear (merino wool or synthetic — cotton underwear in Thai humidity is a bad decision)
• 4–5 pairs of socks (fewer than you think; you'll be in sandals most of the time)
• 1 swimsuit or swim trunks (2 if island-heavy — one dries while you wear the other)
• 1 light packable layer for cold train rides, flights, and air-conditioned restaurants (Thai AC is aggressive; a thin zip-up or cardigan earns its weight)
• Light rain jacket or packable shell

Footwear

• 1 pair of comfortable walking sandals (Chacos, Birkenstocks, or similar — you'll spend hours on your feet and want something with support)
• 1 pair of flip-flops (for beaches, hostel showers, island-hopping; don't walk cities in these)
• 1 pair of closed-toe shoes (for nicer restaurants, nightlife, and anywhere sandals feel out of place; not required if you're purely beach-focused)

Temple etiquette & what to pack for it

Most major temples in Thailand require covered shoulders and knees to enter. Grand Palace in Bangkok enforces this strictly — people get turned away at the gate. Doi Suthep in Chiang Mai does the same. Most smaller wats are more relaxed but some form of respect is expected.

The simple solution: pack one lightweight long-sleeve shirt and one pair of pants or a long skirt. These work for every temple on your itinerary without adding meaningful weight. Many popular temples also lend sarongs at the gate for a small fee — but relying on that for Bangkok's Grand Palace during peak season (long queues) is frustrating.

Shoes must be removed at temple entrances. Slip-on sandals are far easier than lace-ups for temple-hopping days.

Health, safety & insects

• Insect repellent with DEET or picaridin — dengue is real in Thailand and mosquitoes are most active at dawn and dusk; this is not optional in coastal and jungle areas
• Malaria medication — not needed for Bangkok or most popular tourist areas; required if you're trekking in border regions near Myanmar or Laos (consult a travel doctor 4–6 weeks before departure)
• Prescription medications — bring enough for your full trip plus 3–4 days buffer, with copies of prescriptions; Thai pharmacies are good but may not carry your exact brand
• Basic first aid: ibuprofen, antidiarrheal medication (traveler's diarrhea is common in the first week), antihistamine, bandages, antiseptic wipes
• Oral rehydration salts — electrolyte packets are inexpensive in Thailand but worth having for the first day if you land jet-lagged and dehydrated
• Water purification tablets or a Steripen (tap water is not safe to drink anywhere in Thailand; bottled water is cheap and everywhere, but tablets are useful for island situations)
• Travel insurance documentation — Thai hospitals are good in Bangkok and major tourist areas; medical evacuation is expensive without coverage

Toiletries

Thailand is one of the best countries in the world for buying toiletries locally. 7-Eleven sells almost everything. Pharmacies are excellent and inexpensive. Bring what you can't easily replace; buy the rest there.

Bring from home

• Sunscreen — buy a small bottle for the first day; after that, 7-Eleven and pharmacies carry it everywhere at reasonable prices
• Insect repellent (harder to find the right formulation locally in some areas)
• Any prescription or specialty medication
• Feminine hygiene products (available in cities; harder to find on smaller islands)

Buy locally or skip

• Shampoo, conditioner, body wash — available at any 7-Eleven or pharmacy for under $2
• Sunscreen after day 1
• Toothpaste, soap, laundry detergent — buy at the first convenience store you see
• A sarong or lightweight cover-up — the night markets sell these for $3–5 and they're better than what you'd pack

Note: Full-size bottles are fine if you're checking a bag. If you're carry-on only (possible for trips under 2 weeks if you plan laundry), travel-size or solid bars.

Tech & documents

• Passport (valid for at least 6 months beyond your travel dates — Thai immigration checks this)
• Visa: most Western nationalities get a 30-day visa exemption on arrival; confirm your citizenship's current policy before you go; Thailand has expanded e-visa options for longer stays
• Local SIM card or eSIM — buy at the airport on arrival; AIS and DTAC both have tourist SIM packages for ~$15 for 30 days of unlimited data; this is the single best first purchase
• Offline maps downloaded before departure (Google Maps offline covers Thailand well; Maps.me is a solid backup for rural areas)
• Universal power adapter — Thailand uses types A, B, and C outlets at 220V; US plugs often work directly but check your device's voltage range
• Portable battery bank — 10,000mAh minimum; you'll drain your phone on maps, translation apps, and photos
• Phone with Google Translate downloaded offline (the camera translation mode for Thai script is genuinely useful)
• Screenshots or printouts of your accommodation bookings (some guesthouses ask for these at check-in without reliable WiFi)

What changes based on your trip

Island-heavy trips (Koh Samui, Koh Tao, Koh Lanta, Koh Phi Phi) shift the packing toward swimwear and light casual clothing. Bring 2 swimsuits, fewer pants, more quick-dry tops. You'll spend most of your time in a bathing suit or sarong. The temple cover requirement rarely applies on islands.

Northern Thailand (Chiang Mai, Pai, hill tribe trekking) is cooler and sometimes dusty. Add one layer for evenings, comfortable walking shoes for city exploring, and gear for outdoor trekking if that's on your itinerary. Chiang Mai in November–February can feel almost cold after dark by Thai standards.

Bangkok + city days are sweat-intensive. Accommodation almost always has AC, but the streets are extremely hot. Prioritize moisture-wicking fabrics over everything else for city legs. Plan laundry every 3–4 days rather than packing extra clothing.

Multi-country Southeast Asia (Thailand → Vietnam → Cambodia, for example) means packing for varying climates and dress requirements. Vietnam has similar heat with a northern cold season; Cambodia and Laos have temple requirements stricter than Thailand in some cases. If this is your trip, Stow handles each leg separately — enter each destination and it pulls the weather and context for each stop individually.

Wet season vs. dry season changes the rain gear calculation. In dry season (November–April), skip the rain jacket and pack a light sun shirt instead — you're optimizing against UV exposure, not precipitation. In wet season (May–October), the packable rain shell earns its place.
