In Bangkok heat is not an annoyance: it is a fact around which you organise the day. Between March and May the thermometer regularly passes forty degrees, and air conditioning is not enough. Swimming then becomes the best solution, provided you know where to go: not all pools are equal, and some water is to be avoided.
Why swimming changes a day
An hour in cool water lowers body temperature and lets you face the afternoon. For a traveller it is also a pause in a tiring city: nothing is visited, nothing is walked, you recover. This is especially true with children, for whom heat is harder and who have no patience for a museum at two in the afternoon.
Public pools
Bangkok has municipal pools, often attached to neighbourhood sports centres. They are simple, clean, cheap and very quiet on weekdays, with a lap pool, sometimes a children’s pool, and changing rooms. Comfort varies a lot from one area to another: ask on site or check opening hours by phone, as pools sometimes close for maintenance.
Hotel pools
The simplest solution for a visitor: most mid-range and upscale hotels have a pool, often on the roof, sometimes in a courtyard. If you are a guest, access is included; otherwise some establishments sell day access. Rooftop pools offer a view worth the trip, but they are often small and sometimes closed to outside visitors. Call before crossing the city.
Water parks
Bangkok has several water parks, on the outskirts, with slides, wave pools and children’s areas. It is a full family outing, occupying half a day and costing more than a neighbourhood pool. They are very busy at weekends; on weekdays queues are short.
Residence pools
Many recent buildings have a pool reserved for residents. Some owners rent them with short stays, but access is not open to the public. If you book an apartment, check that the pool is really accessible and not just visible in the photos.
Clubs and sports centres
Private clubs, often inside hotels or sports complexes, open their pools by the day or month. They offer proper lap pools, showers, sometimes a gym. An interesting option for a long stay.
What to avoid
The river, the canals and park ponds are not swimming spots: polluted water, currents, unbuilt banks. Thai people themselves do not swim there. In Bangkok, swimming happens in pools and nowhere else.
With children
Safety first: choose a pool with a small basin and, if possible, a lifeguard, and avoid peak hours. Never leave a child unattended, even in twenty centimetres of water. Bring armbands, water-resistant sunscreen and a full change.
Rules
Most Thai pools require proper swimwear, a shower before entering, and forbid street shorts. Some provide caps, others require them. In small public pools, rules may be in Thai only: imitate other swimmers.
Cost
A public pool costs a few euros, sometimes less. A hotel pool is included in the room or charged by the day. Water parks are the most expensive, with family rates.
Opening hours
Public pools often open early and close in the late afternoon. Hotel pools are open during the day, sometimes into the evening. Water parks open mid-morning and close late afternoon.
When it rains
Monsoon showers are short but intense, and outdoor pools close during storms. Wait an hour: the rain passes, the water stays warm and crowds thin.
Alternatives
Without pool access, shopping malls offer artificial coolness, and so do cinemas, and some temples have shaded courtyards. But nothing replaces an hour in the water.
A typical day
Morning: early visits. Noon: lunch in cool air. Two: pool or water park. Five: back outside as heat drops. It is the rhythm Bangkokians follow themselves.
Mistakes to avoid
Swimming in the river. Going to a public pool without checking hours. Forgetting that street swim shorts are sometimes refused. And believing a hotel pool is open to all.
