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.

Nong Chok flood risk — frequently asked questions

Does Nong Chok flood in Bangkok?▾

Nong Chok 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 Nong Chok affected by the 2011 Bangkok flood?▾

Yes. Nong Chok 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 Nong Chok?▾

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 Nong Chok score tells you the baseline you are starting from.
