Bangkok Travel Tips
When to Go, Budget, SIM, Temples, Taxis

🔄 Updated 21 Jun 2026

First, the quick big picture. Bangkok sits in central Thailand and the weather splits into three seasons: cool (Nov–Feb), hot (Mar–May), and rainy (Jun–Oct). The difference from other places is that Bangkok never actually gets cold — at most you get a pleasant cool in the early morning, and it stays hot and humid most of the year. So choosing a month in Bangkok isn't about temperature, it's about rain and how comfortable it is to walk around.

First things first — which month to go

If you want the most comfortable time to visit Bangkok, the answer is clear: the cool season. It's the only stretch with little rain and low humidity, so you can walk temples and outdoor markets without suffering. Here's an honest rundown of each period.

• November–February (cool season · the best) — daytime around 28–32°C, clear skies, little rain, low humidity, the easiest time to be outdoors. This is the real high season, so rooms fill up and prices climb, especially December through early January — book ahead.
• March–May (hot season) — very hot and humid, daytime hitting 35–40°C, and walking in the midday sun is exhausting. But if you want to join Songkran around April 13–15, the water fights on Silom and Khao San roads are a blast. Plan trips around malls, museums, and outdoor stuff only in the early morning or evening.
• June–August (early rainy season · best value) — low season, with rooms noticeably cheaper, some 40–50% off. The rain usually comes in short bursts in the afternoon or evening, not all day, so plan around an umbrella and you'll still get plenty done.
• September–October (late rainy season · be careful) — the heaviest and most frequent rain of the year, with some days raining for hours and the occasional flooding in parts of the city. If you go now, always have an indoor backup plan ready.

Rain and traffic — the two things that eat the most of your trip

Honestly, the real enemy of a Bangkok trip isn't the heat — it's rain and traffic. The two always come together, because the moment it rains the traffic gets worse, especially around the evening rush. Understanding their rhythm helps you plan your days a lot better.

• Rain usually falls in the afternoon and evening — Bangkok's rainy season comes in downpours in bursts, rarely all day. Schedule outdoor activities in the morning, then keep an indoor backup (mall, café, museum) for the afternoon.
• Rush hour traffic is brutal — roughly 7–9 a.m. and 4:30–8 p.m., cars on the road barely move and a 5 km stretch can take an hour. Avoid riding in cars during these windows and take the BTS/MRT instead.
• Rain + rush hour = disaster — on a rainy evening, Grab prices surge and cars are hard to get. If your timing lines up with this, ducking into a Skytrain station is much faster and more reliable.
• Saen Saep canal boats / river boats — a shortcut a lot of people forget. During traffic, the Chao Phraya express boat and the Saen Saep canal boat beat the roads on many routes.

Getting around the city — BTS, MRT, boats, Grab, taxis

Bangkok has a full set of transport options, each suited to a different situation. Here's a rundown of what to use when, with rough prices.

Taxis and safety — what tourists run into most

Bangkok is generally safe for tourists, and walking at night around the main areas is fine. But where people get scammed most is taxis and the various scams around the big tourist sites. Know them ahead of time and you'll dodge almost all of it.

• Taxis that won't run the meter — the classic problem: the driver quotes a flat fare several times higher than the meter. If they won't turn the meter on, get out and flag another, or just open Grab/Bolt instead — it's simpler.
• Scams at the airport — people standing in the arrivals hall asking "Taxi?" aren't real drivers, and the price they offer is several times the app rate (there have been cases of 800–1,500 THB when the app showed 350). Walk to the airport's public metered-taxi stand, or book the app yourself.
• The "temple is closed" scam — someone dressed to look official tells you Wat Phra Kaew or Wat Pho is closed today, there's a ceremony, it reopens at 1 p.m., then offers a tuk-tuk to somewhere else. It's a lie — walk up to the real entrance and check for yourself. The major temples post their opening hours at the gate.
• Gem-shop / tuk-tuk tour scams — someone friendly chats you up near a tourist site and steers you to a gem shop with a "special discount, today only" or offers a suspiciously cheap tuk-tuk that loops you through shops for commission. If someone offers something too good to be true, walk away.

Temple dress — what actually gets you in

This matters and people get it wrong a lot, especially at Wat Phra Kaew and the Grand Palace, which are the strictest and enforce it on everyone. Wear the wrong thing and you don't get in — you'll have to rent or buy a cover-up at the entrance, which wastes time and sours the mood. Better to get it right before you leave your room.

• The general rule — cover your shoulders and knees, men and women alike. No tank tops, no sleeveless shirts, no shorts or skirts above the knee, no see-through tops, and no thin tight leggings.
• Wat Phra Kaew and the Grand Palace (strictest) — you need long trousers or a long skirt and a shirt with sleeves that covers the shoulders. Here a shawl alone usually won't pass; they want an actual sleeved top. If you turn up in the wrong thing, you'll have to rent a wrap at the entrance.
• Wat Pho / Wat Arun — also strict about covered shoulders and knees, but a little more flexible. A shawl can pass in some spots, but coming dressed properly from the start is safer.
• Forgot to bring it? — there are stalls selling elephant pants, thin long-sleeve tops, and sarongs near the temple entrances for about 100–250 THB. Buy something to wear and you've got a souvenir too.

Roughly how much per day

A Bangkok budget is very flexible, because there's everything from street food costing a few baht a plate to Michelin restaurants. The figures below are per person per day, not including airfare but including accommodation (split two ways for a couple), food, getting around the city, and a reasonable amount of admission fees. Use it as a rough frame and adjust to your own style.

What to wear — for Bangkok's weather

Bangkok is hot and humid almost all year, so dressing here is different from Chiang Mai or the north — keep it light and breathable. You barely need to think about warm clothing, except for the malls and trains where the air-conditioning is freezing.

• Year-round (hot and humid) — thin, light, breathable, light-colored clothes; pick fabrics that wick sweat and dry fast. Comfortable walking shoes, because you'll walk a lot in a day. Bring a hat and sunglasses.
• In malls / on trains — the air-conditioning is very cold, so pack a thin layer or a scarf in your bag for when you're indoors for a while.
• Rainy season (Jun–Oct) — add a folding umbrella or a light rain jacket and shoes that dry quickly when wet. Skip leather or canvas shoes that soak up water, since some streets pool with water.
• Temples — always have a sleeved top that covers the shoulders and trousers or a skirt that covers the knee (see the temple dress section above). If you're planning Wat Phra Kaew that day, dress fully from the morning.

SIM / internet — what to choose

Bangkok has good signal on every carrier across the city, so Thais who already have a SIM barely need to do anything. Foreign visitors have these main options, and prices are cheap compared to a lot of countries.

• Already have a Thai SIM — just use it; check you have enough data left. In the city, every carrier's signal is about equally good.
• Tourist SIM — AIS, True/dtac have tourist packages with plenty of data for several days. Prices at the Suvarnabhumi/Don Mueang airport counters run about 250–900 THB depending on days and data — for example, AIS starts around 299 THB for 15GB over 8 days. Since mid-2025, buying a SIM requires showing your passport to register everywhere.
• eSIM — the most convenient for newer phones that support it. Install it ahead of time from home before you fly, then activate it on landing with no airport queue. There are options from both Thai carriers and global providers like Airalo, starting at a few dollars.
• 7-Eleven / convenience stores — you can buy prepaid SIMs and top up data all over the city, handy in a pinch, but the package choices are fewer than at the airport carrier counters.

What to pack — a checklist

Almost everything is cheap and easy to buy in Bangkok, so you don't need to haul much. But a few things will be annoying if you forget them. Here's what people tend to forget or should keep in their bag.

Small things that make the trip smoother

• Download Grab + Bolt before you go — have both to compare prices, see the fare before you tap, and skip haggling with taxis.
• Pick accommodation near the train — Sukhumvit (Asok–Thonglor) or Silom–Sathorn are the most convenient and cut traffic problems a lot.
• Do the old town in the morning — Wat Phra Kaew, Wat Pho, Wat Arun: go early to dodge both the midday sun and the crowds, and note some temples close mid-afternoon.
• ICONSIAM / riverside malls have free shuttle boats — from Sathorn pier (BTS Saphan Taksin) you can take a free shuttle boat to ICONSIAM — cheap and a nice view.
• Watch the traffic on Friday evenings and long weekends — if you have to head to the airport then, leave plenty of extra time or take the Airport Rail Link.
