Bangkok in November runs an average high of 30.1°C (86°F) and an average low of 22.9°C (73°F), with 162.4 mm of rain spread across roughly 12 days of the month. Three things determine what you pack: the humidity never lets your clothes dry, the rain arrives in short heavy bursts rather than all-day drizzle, and indoor air conditioning is aggressive enough that you will feel cold in a way the outdoor numbers never suggest. Pack fast-drying fabrics, one packable rain layer, and one long-sleeve item you can throw on inside malls, buses, and temples.
What the weather is actually like
November is the handover month. The southwest monsoon that soaks central Thailand from May through October is winding down, and the cool dry season is starting. The 162.4 mm of rainfall in Bangkok sounds like a lot to anyone used to a temperate climate, but it falls on about 12 days, which means most of the month is dry and the wet days tend to concentrate the water into an hour or two of hard rain, usually in the late afternoon.
The 22.9°C average low matters more than it looks. That low happens around dawn, and it is the first month of the year where early mornings in Bangkok feel genuinely pleasant rather than oppressive. If you have an early flight, a sunrise temple visit, or a long-tail boat trip that starts at 6 a.m., a light layer earns its space. By 11 a.m. you will be back at 30°C and want it off.
The number that does not appear in any climate table is humidity, and it is the one that changes your packing decisions most. Cotton that gets sweaty at noon will still be damp at 8 p.m. Denim is worse. Anything you wash in a hotel sink will not dry overnight unless the room has air conditioning running.
One honest caveat about geography: these numbers are Bangkok. Thailand's east coast islands — Koh Samui, Koh Phangan, Koh Tao — run on a different monsoon cycle, and November is one of their wettest months, not one of their driest. If your trip is Bangkok plus Chiang Mai plus Phuket, November is close to ideal. If your trip is Bangkok plus Koh Samui, expect the island half to be considerably wetter than the numbers above, and plan an indoor backup day.
What to Wear in Thailand in November, Layer by Layer
Base layer. Synthetic or merino blend, not cotton. Three or four short-sleeve tops is enough for a two-week trip, because you will be doing laundry regardless and synthetics dry in a few hours where cotton takes a full day. Two pairs of lightweight trousers or long shorts, plus one pair of quick-dry shorts for beach or pool days.
The temple layer. Thailand's major temples enforce a dress code: shoulders covered, knees covered, for everyone. Bangkok's Grand Palace is strict about it and will make you rent a cover-up at the gate. Pack one pair of lightweight long trousers and one shirt or scarf that covers the shoulders and treat that as a fixed outfit rather than something you improvise. Loose linen or a technical travel trouser works; anything tight will be miserable at 30°C.
The indoor layer. This is the November-specific one people miss. A light long-sleeve shirt or thin cardigan, packed at the top of your bag, not the bottom. Thai malls, cinemas, long-distance buses, and overnight trains are cooled hard, and the difference between a 30°C street and a 20°C bus is jarring. With a dawn low of 22.9°C, this layer also covers early mornings in Bangkok — and if you are heading north to Chiang Mai or Pai, November nights there are meaningfully cooler than Bangkok's, so it stops being optional.
Rain layer. A packable rain jacket or, more practically, a cheap poncho. With 12 rainy days spread through the month, you are likely to catch two or three downpours on a two-week trip. Umbrellas are sold on every corner in Bangkok for a few dollars, so there is a fair argument for buying one there instead of packing one.
Feet. Sandals that survive getting wet, plus one closed pair for walking days. Leather shoes are a bad choice in this humidity — they stay damp and start to smell. Streets flood ankle-deep during hard rain, so if you only bring one pair, make it the one you do not mind soaking.
What most people get wrong for this month specifically
Treating November as the dry season. It is the start of it, not the middle of it. December and January are drier. Travelers who read "cool dry season" and pack zero rain gear get caught by the 162 mm that still falls. The rain does not ruin trips in November, but it will ruin an unprotected camera or laptop bag.
Assuming "cool season" means cool. A 30.1°C average high is not cool by any normal definition. The Thai cool season is cool relative to April, when Bangkok regularly clears 35°C. People pack jeans and closed shoes on the strength of the word "cool" and then wear neither.
Ignoring the islands split. As above, the Gulf coast islands are in their wet season in November. Booking a Koh Samui beach week for early November because "November is Thailand's dry season" is a common and expensive mistake.
Underestimating the sun. Cooler air makes the sun feel less intense than it is. Bangkok sits at about 13.7°N; the UV index stays high through November. High-SPF sunscreen is expensive and hard to find above SPF 50 in Thai pharmacies, and much of what is sold locally contains skin-whitening agents. Bring your own.
Packing for one climate. If your itinerary includes northern Thailand, you are packing for two. Chiang Mai and especially the mountains around Pai and Chiang Rai get noticeably cooler after dark in November than Bangkok's 22.9°C low. One warm layer covers it.
What you can skip
Heavy rain gear. Rain pants, waterproof boots, a serious hardshell — all overkill for a month where the rain is warm and brief. You dry off in twenty minutes.
More than a week of clothes. Laundry in Thailand costs a few dollars for a full bag and turns around in a day. Packing fourteen outfits for fourteen days is the single biggest source of overweight bags on this route.
A hair dryer, travel iron, or full-size toiletries. Every hotel and most guesthouses have a dryer. Shampoo, soap, and toothpaste are cheap at 7-Eleven, which is on essentially every block in Bangkok.
A universal power adapter, mostly. Thai outlets take both flat two-prong (Type A) and round two-prong (Type C). If your devices use either, you can plug straight in. UK three-pin plugs do need an adapter.
Bug spray in bulk. Mosquitoes are present, particularly at dusk and after rain, but DEET-based repellent is sold everywhere and locally sold products are effective. Bring a small bottle for the first evening.
A sleeping bag liner or towel, unless you are staying in budget hostels. Mid-range hotels supply towels, and it is dead weight otherwise.

- Sandals that tolerate getting soaked, plus one closed walking pair
- High-SPF sunscreen brought from home
- Small bottle of DEET repellent
- Dry bag or waterproof phone pouch for boats and afternoon downpours
- Refillable water bottle
- Power bank — long travel days and constant map use drain a phone fast
- Any prescription medication in original packaging, with the prescription
- Basic first aid: rehydration salts, anti-diarrhoeal, plasters
Frequently Asked Questions
Is November a good time to visit Thailand?
For central and northern Thailand and the Andaman coast, yes — it is one of the better months. Bangkok's 30.1°C high with rain on about 12 days of the month is a marked improvement on September and October, and the humidity begins easing. The honest exception is the Gulf coast islands, where November is among the wettest months of the year. If beach time on Koh Samui or Koh Phangan is the point of the trip, another month serves you better.
Do I need a rain jacket for Thailand in November?
Something waterproof, yes; a serious rain jacket, no. With 162.4 mm falling over roughly 12 days, most downpours are short and warm, and a poncho or cheap umbrella handles them. What genuinely needs protection is electronics — a dry bag or waterproof pouch matters more than what you wear.
What is the difference between packing for Thailand in November versus March?
Two things change. March is hotter and drier, on the ramp toward April's peak heat, so rain gear becomes near-irrelevant and heat management is the whole problem. November still carries real rainfall and, with lows around 22.9°C at dawn plus cooler nights in the north, actually justifies a light warm layer that March does not. Pack the long-sleeve and the poncho for November; skip both in March and add an extra shirt instead.
