Boston Spa Climate Risk Data

Boston Spa is a town in North Yorkshire, within North Yorkshire council area. This page shows flood, heat, air quality, and subsidence risk data for Boston Spa, drawn from official UK government sources. LocalRisk tracks 12 postcodes within Boston Spa.

Boston Spa has relatively low flood risk based on Environment Agency NaFRA2 data. 5.7% of postcodes in Boston Spa fall into high or higher flood risk bands, with a further 2.9% at medium risk and 91.4% at lower risk. Flood risk at street level can differ significantly from these area-wide averages — elevation, proximity to watercourses, and local drainage all affect individual postcode risk bands. Check a specific postcode above for your exact Environment Agency flood risk rating.

Heat risk in Boston Spa is relatively low under current projections. Met Office UKCP18 data suggests around 12 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 Boston Spa without adequate ventilation or insulation may face increasing summer heat stress and higher cooling costs as temperatures rise.

Air quality in Boston Spa averages 5.5 µg/m³ PM2.5, which is relatively low — above 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 Boston Spa 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. Check a specific postcode for Boston Spa for a property-level subsidence risk band.
