Bangkok flood check

Does Bang Bon flood? Risk level 4 of 5

L4High — significant 2011 + recurring waist-deep flooding

Bang Bon is high risk. It was significantly inundated in the 2011 great flood and still sees recurring waist-deep water in the worst monsoon weeks. Ground-floor and podium units need a hard look, and past water is a question to put to the juristic office.

Ranked 10 of 50 Bangkok districts, riskiest first.

How this level is set

RealData scores each of Bangkok’s 50 khet from 0 to 5 against BMA Drainage Department records, JICA flood-frequency reports and 2011 great flood inundation mapping. The layer is district-level, not coordinate-level, and is reviewed once a year after the BMA monsoon report.

Bang Bon flood risk — frequently asked questions

Does Bang Bon flood in Bangkok?▾

Bang Bon is high risk. It was significantly inundated in the 2011 great flood and still sees recurring waist-deep water in the worst monsoon weeks. Ground-floor and podium units need a hard look, and past water is a question to put to the juristic office.

Was Bang Bon affected by the 2011 Bangkok flood?▾

Yes. Bang Bon 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 Bon?▾

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 Bon score tells you the baseline you are starting from.
