Prestatyn is a settlement in Denbighshire, within Denbighshire council area, situated on the UK coastline. This page shows flood, heat, air quality, and subsidence risk data for Prestatyn, drawn from official UK government sources.

Flood risk in Prestatyn is rated Lower based on Environment Agency data for the Denbighshire area. Individual postcode flood risk can vary — check a specific address above for a postcode-level rating.

Heat risk in Prestatyn is relatively low under current projections. Met Office UKCP18 data suggests around 10 days above 25°C per year in this area by the 2021-2040 period (central estimate, high emissions scenario). These are probabilistic projections — actual outcomes depend on future emissions levels. Properties in Prestatyn without adequate ventilation or insulation may face increasing summer heat stress and higher cooling costs as temperatures rise.

Air quality in Prestatyn averages 4.9 µg/m³ PM2.5, which is relatively low — meeting the WHO annual mean guideline of 5 µg/m³. Defra UK-AIR monitoring data underpins this figure. PM2.5 levels are typically higher near busy roads, industrial areas, and dense urban centres, and lower in parks, green corridors, and residential backstreets.

Subsidence data for Prestatyn is sourced from the British Geological Survey GeoSure dataset, which maps clay shrink-swell risk across Great Britain. In areas with shrink-swell clay, foundations can shift as soils dry out in summer and re-wet in winter. Properties built before 1980 on clay-rich ground are most exposed.
