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.

Watthana flood risk — frequently asked questions

Does Watthana flood in Bangkok?▾

Watthana carries low risk. Expect ankle-deep puddling on the smaller sois during a hard monsoon downpour, draining the same day. It was not part of the 2011 inundation zone.

Was Watthana affected by the 2011 Bangkok flood?▾

Largely no. Watthana 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 Watthana?▾

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 Watthana score tells you the baseline you are starting from.
