Bangkok flood check

Does Bangkok Yai flood? Risk level 3 of 5

L3Moderate — neighborhood-level flooding common

Bangkok Yai floods at neighbourhood level. Several times a monsoon season individual sois hold water for hours; ground-floor parking and garden units are the exposure. Not a reason to rule the district out — a reason to check the building’s own ground level.

Ranked 25 of 50 Bangkok districts, riskiest first.

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.

Bangkok Yai flood risk — frequently asked questions

Does Bangkok Yai flood in Bangkok?▾

Bangkok Yai floods at neighbourhood level. Several times a monsoon season individual sois hold water for hours; ground-floor parking and garden units are the exposure. Not a reason to rule the district out — a reason to check the building’s own ground level.

Was Bangkok Yai affected by the 2011 Bangkok flood?▾

Largely no. Bangkok Yai stayed outside the worst of the 2011 inundation, protected by elevation and the King’s Dyke barrier line. Its current level reflects that.

Is it safe to buy a condo in Bangkok Yai?▾

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 Bangkok Yai score tells you the baseline you are starting from.
