Air quality in Shoreham-by-Sea averages 6.6 µg/m³ PM2.5, which is moderate — 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 Shoreham-by-Sea 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.
