Bangkok

How the city is arranged

Forget the map. What matters is whether a place is on the river, on a rail line, or neither — and 'neither' means budgeting an unpredictable amount of time to reach it.

• Rattanakosin — the old royal city, the palace and the big temples. On the river, not on the rail network.
• The river itself — express boats are fast, cheap and scenic, and often the quickest way across the city.
• Sukhumvit and Silom — modern Bangkok along the Skytrain lines. Food, malls, and where most people stay.
• Thonburi, across the river — quieter canals and a different pace, ten minutes and a world away.

When to go, and what each season costs you

Bangkok has three seasons, not four, and they are unusually distinct. None of them is cold; the question is heat versus water.

• November to FebruaryGo now

  The cool dry season — and it is genuinely better

  Lower humidity, little rain, and temperatures that make walking the old city possible. This is peak season for a reason: it is the only window where a full outdoor day is comfortable. Book ahead, especially around the turn of the year.

• OctoberWorth it, but

  The monsoon tailing off

  Rain is easing and the crowds have not arrived. A good-value gamble if you can move an afternoon indoors when it pours.

• June to SeptemberWorth it, but

  Monsoon: heavy, brief, and cheap

  The rain is usually intense but short — an hour in the afternoon rather than an all-day drizzle — and everything is noticeably cheaper and emptier. Flooding in low-lying streets is the real disruption, not the rain itself.

• March to MayThink twice

  The hot season, which is hotter than you think

  The hardest months: extreme heat with high humidity and little wind. Songkran, the Thai new year water festival, falls in mid-April and is genuinely worth experiencing — but much of the country shuts down around it and travel gets difficult.

Things that change the trip

• Build each day around one rail line or the river. Crossing the city at rush hour can take an hour for a few kilometres.
• River express boats are a public transport system, not a tour. They are the fastest way to reach the old city from the centre.
• Temples enforce dress codes: covered shoulders and knees. Being turned away at the gate is a common and avoidable waste of a morning.
• Metered taxis are cheap but the meter has to be running. Ride-hailing apps avoid the negotiation entirely.
• Street food is at its best in the evening, and the safest heuristic is the same everywhere: a long queue of locals and high turnover.
