Does Bang Khun Thian flood in Bangkok?▾

Bang Khun Thian is among the most flood-exposed khet in Bangkok. Repeat full-area inundation during monsoon season is on record, including weeks of standing water in 2011. Buy here on price, with eyes open — not on the assumption that it stays dry.

Was Bang Khun Thian affected by the 2011 Bangkok flood?▾

Yes. Bang Khun Thian sits inside the 2011 inundation zone — the flood that reached the northern and eastern khet and held for weeks. Its current level reflects that history.

Is it safe to buy a condo in Bang Khun Thian?▾

Flood level is one input, not a verdict. Check the building itself: ground-floor height above the soi, whether parking is at grade, and what the juristic office says about past water. The Bang Khun Thian score tells you the baseline you are starting from.
