Bangkok flood check

Does Yan Nawa flood? Risk level 3 of 5

Also written Yannawa.

L3Moderate — neighborhood-level flooding common

Yan Nawa 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 37 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.

Yan Nawa flood risk — frequently asked questions

Does Yan Nawa flood in Bangkok?▾

Yan Nawa 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 Yan Nawa affected by the 2011 Bangkok flood?▾

Largely no. Yan Nawa 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 Yan Nawa?▾

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 Yan Nawa score tells you the baseline you are starting from.
