Bangkok
September is a soaking, cheap, half-empty Bangkok — and the Grand Palace finally breathes.
When to visit Bangkok
Bangkok is calmest in September and busiest in December. For the best balance of decent weather and smaller crowds, aim for June.
Bangkok runs on the monsoon calendar, not the European one. The cool dry season from November to February is the peak: warm days, tolerable humidity, almost no rain, and hotel rates to match. December and January are the fullest weeks of the year, and riverside rooms go months in advance.
Then the heat arrives. March through May is the hot season, with April the hottest month in the country and Songkran splitting it in two — the city empties as people travel home for the new year, then fills again with water fights. From May the rains build, peaking in September at over twenty wet days, and that is the deepest low season of all.
The overlooked windows are late October into early November, when the rain stops before the crowd returns, and the last two weeks of February, when the cool season is still holding but the Christmas rush is long gone.

How long to stay
Three days is enough for the temples, the river and the markets; four or five if you want Ayutthaya or the floating markets as day trips.
Local timing tips
- Use the river. The Chao Phraya express boats and the BTS and MRT lines together beat any taxi in a city where surface traffic is the main constraint on your day.
- The Grand Palace enforces a dress code — covered shoulders and knees, for everyone — and the cover-up rental queue outside is long. Wear the right clothes and walk straight in.
- Do the outdoor half of your day before 11am. From noon the heat index is punishing in every month, not only in the hot season.
- Rain almost always comes as a sharp late-afternoon storm rather than an all-day soak, so build a mall, a museum or a massage into the 3pm to 5pm slot in the wet months.
