Of Phetchaburi's 7 districts, 5 have a high estimated chance of river flooding and 0 a high chance of flash flooding. The highest risk is in Cha-Am, where the river flooding level is High (estimated).
The 2024 observed flood event covers only four northern provinces (Chiang Mai, Chiang Rai, Lamphun, and Phayao); flash-flood terrain indicators are modelled from nationwide terrain data and are not a forecast. OpenStreetMap contributors
Ban Lat has the highest Flash-flood terrain susceptibility in Phetchaburi, at Moderate.
Kaeng Krachan has the lowest Flash-flood terrain susceptibility in Phetchaburi, at Minimal.
Terrain-derived flash-flood indicators (HAND + slope + OSM drainage proximity; NOT a forecast or probability, not calibrated against observed events) from Copernicus DEM GLO-30 (via Mapterhorn terrain tiles) and OpenStreetMap waterway data. The banded metric flags whether the region CONTAINS terrain susceptible to flash flooding somewhere within it -- not the susceptibility of the region as a whole, and not of any individual property.

In Phetchaburi, 5 districts have a high estimated chance of river flooding and 0 districts have a high estimated chance of flash flooding.
5 districts in Phetchaburi have a high estimated chance of river flooding, including Cha-Am.
Topographic view shades terrain by elevation — higher, steeper ground is generally less exposed to flooding, while low-lying land near watercourses is more exposed.
5 districts in Phetchaburi have a high estimated chance of river flooding, including Cha-Am.
No districts in Phetchaburi currently have a high estimated chance of flash flooding.
Cha-Am in Phetchaburi has the highest single hazard estimate, a High level of river flooding.
Each district gets a Low, Medium, or High estimate for every hazard. "Observed" levels come from a directly measured event, such as a satellite-recorded flood extent. "Estimated" levels are modelled from proxies such as terrain, historical rainfall, or monitoring-station readings, and are not a forecast or a probability. A level never combines more than one hazard, and "Not enough data yet" means exactly that — not a safe rating.
A High estimate for Phetchaburi is a prompt to ask more questions — request a site-specific flood or engineering survey, check the property's ground floor level and past flood history with the seller or agent, and review local drainage before committing. A Low estimate does not guarantee a property is risk-free, and none of these levels replace a professional inspection.

The river flooding estimate for Phetchaburi's highest-risk district is estimated.
No districts in Phetchaburi currently have a high estimated chance of flash flooding.
The flash flooding estimate for Phetchaburi's highest-risk district is estimated.
Cha-Am in Phetchaburi has the highest single hazard estimate, a High level of river flooding.
In areas of Phetchaburi with a High hazard estimate, ask for a site-specific survey and the property's flood history before committing — a High estimate is a prompt to investigate further, not a verdict on any single property.
The hazard estimates for Phetchaburi are sourced from Terrain-derived flash-flood indicators (HAND + slope + OSM drainage proximity; NOT a forecast or probability, not calibrated against observed events) from Copernicus DEM GLO-30 (via Mapterhorn terrain tiles) and OpenStreetMap waterway data.

Low, Medium, and High are screening estimates, not a forecast or probability. Each hazard is scored on its own — there is no single combined risk score across hazards.
