Gwynedd, Harlech
Heat risk is Lower. Air quality is Low at PM2.5 4.3 μg/m³, within the WHO annual guideline of 5 μg/m³ (Defra UK-AIR).
An official flood-risk band is not available for LL46 2AD in the current dataset releases used by LocalRisk. This is a data-coverage gap rather than a low-risk rating. For a property-level reading, Natural Resources Wales' Flood Risk Assessment Wales map covers every address in Wales.
Air quality at LL46 2AD is rated Low, based on Defra UK-AIR annual mean PM2.5 data. Fine particulate matter (PM2.5) comes primarily from road traffic, industry, and domestic burning. Long-term exposure above the WHO guideline of 5 µg/m³ is linked to respiratory and cardiovascular health risks. Buyers and renters in higher air quality risk areas may wish to consider whether the property is near busy roads or industrial sources.
This LocalRisk report for LL46 2AD draws on four official UK open data sources: Natural Resources Wales flood mapping, Met Office UKCP18 climate projections, Defra UK-AIR PM2.5 monitoring, and British Geological Survey GeoClimate subsidence mapping. Risk ratings are a screening tool, complementing - not replacing - the searches and surveys ordered as part of a property transaction. Data covers Gwynedd and is updated as new official datasets are published.
Gwynedd has a predominantly upland and coastal setting with mountains, river valleys and dispersed settlements and experiences cool, wet winters and mild summers, shaped by Atlantic weather and steep catchments.
