Bangkok

Bangkok is a low-rise sprawl of 1,569 square kilometers with a dense vertical spine grafted onto it along the rail lines, and the lived experience splits sharply along that spine. Within 400 meters of a station, life is efficient, air-conditioned and mall-mediated. Beyond it, the city becomes long sois, no pavements worth the name, and dependence on motorbike taxis.

Proximity to a rail station is the single highest-leverage decision a resident makes here, because rail journeys are predictable and road journeys are not. Everything else on this page is downstream of that.

Who Bangkok suits

It works for people on a foreign or corporate salary who want a genuinely large city — world-class food, the best medical care in the region, the deepest international school infrastructure in Southeast Asia, direct flights almost everywhere, and 24-hour convenience. It works for families, and for anyone whose work requires a real business center rather than a lifestyle destination. It works for people who are indifferent to walking and happy to move between air-conditioned interiors.

It works badly for anyone who wants to walk daily for pleasure — the pavements and the heat make that genuinely unpleasant for most of the year. For anyone sensitive to particulates, because the December to March season is severe. And for retirees on tight fixed incomes, who get materially more for their money in Chiang Mai or the provinces.

The heat is chronic, not seasonal

This is the fact most visitors misjudge because they came in November. Average daily highs never drop below 32.3 C in any month, and peak at 35.8 C in April. In April 2026 the Bangkok Metropolitan Administration recorded the heat index in its “Danger” band for 18 consecutive days, peaking at 51.9 C, and advised stopping outdoor activity between 11:00 and 15:00.

The year has a shape worth learning: December to March is the pollution season, March to May the extreme heat, May to October the rains with routine street flooding, and November to early December the short window that is genuinely pleasant. There is no season that is comfortable and clean and dry at once, except that one.

The walkability problem is real

Not a quibble — a structural constraint on how you will live. Pavements across most of the city are uneven and obstructed by parked motorbikes, vendor carts, utility poles and drainage grates, with sudden unramped drops. Signalised pedestrian crossings on major arteries are rare and drivers do not reliably yield at the ones that exist.

Then there is the geometry: Bangkok’s superblock layout means soi mouths are often 500 meters to a kilometer apart, so two points 200 meters apart as the crow flies can be a 1.5 km walk. Add 33 to 36 C and 65 to 78 percent humidity and daily walking becomes realistic only in short bursts between air-conditioned spaces.

Where to live

Sukhumvit is where most Western and Japanese arrivals land, and it is not one place — Asok, Phrom Phong, Thonglor, Ekkamai and On Nut are genuinely different in cost, noise and character. Sathorn and Silom are the financial and diplomatic district. Ari is the low-rise, tree-lined, more Thai option and the most walkable part of the city. Ratchathewi is the cheapest genuinely central address. Bang Na is the family suburb, chosen for school catchment. Full detail with 2026 rents and the trade-off on each.

An ordinary week

Work; a couple of gym or Muay Thai sessions; food, which is the city’s actual center of gravity — a street cart for breakfast, a shophouse or food court for lunch, a rotating list for dinner; a weekend market; and for the outdoors-inclined, a very early run in Lumphini or Benjakitti before the heat arrives.

The single best answer to “where do I go to not be in Bangkok for a day” is Bang Krachao, the Green Lung — a 16 square kilometer river-bounded peninsula reached by a four-baht ferry, with elevated cycle paths through mangrove. More, including the markets residents actually use.

The community, and its boundary

Worth being precise, because the word “expat” flattens something important. Thailand’s foreign population is overwhelmingly migrant labor — Myanmar, Cambodian and Lao — with Western expatriates numbering roughly 200,000 nationally. In Bangkok, Japanese nationals are the largest single non-labor foreign community, centered on the Phrom Phong and Thonglor corridor, followed by Chinese, Korean and Indian communities.

On making Thai friends: harder than the surface friendliness suggests. Thai social life is organized around family, workplace and school cohorts, which are difficult to enter laterally. The people who succeed are learning Thai, doing a shared activity with Thais — Muay Thai gyms, running clubs, badminton, climbing — or working somewhere Thai-majority. The expat and Thai social boundary in Sukhumvit is real and self-reinforcing; Ari, Ratchathewi and the Thonburi side are noticeably more mixed.
