Other Settlement CLIMATE RISK
North Stoneham is a settlement in Hampshire, part of the Eastleigh council area.
North Stoneham inherits its flood band (Medium) from the wider Eastleigh council area because the Environment Agency does not publish settlement-level breakdowns for every UK location. Search any postcode in North Stoneham below for the address-level reading from Environment Agency NaFRA2.
Met Office UKCP18 projections estimate around 32 days above 25°C per year across the Eastleigh area for the 2021-2040 period - the central scenario under high emissions; lower-emissions paths give lower numbers. Heat exposure within North Stoneham itself is uneven: top-floor flats, west-facing terraces and properties without through-ventilation hold heat well into the night, while ground-floor homes near tree cover or open ground cool faster. The headline 32-day figure is an area average, not a property-level reading.
Annual mean PM2.5 across the Eastleigh area is 6.4 µg/m³ - close to the World Health Organisation guideline of 5 µg/m³ and within the UK Environment Act 2021 target of 10 µg/m³ by 2040. Within North Stoneham, readings are not flat: postcodes within 200 metres of an A-road or major junction routinely run 30-50% higher during weekday rush hours than residential streets two roads back. Defra's UK-AIR network supplies the underlying figure.
Ground stability in North Stoneham follows the underlying geology more than the postal boundary. The British Geological Survey GeoSure dataset maps clay shrink-swell risk on a 50-metre cell, and properties on the same street can sit in different bands where a clay seam ends mid-road. Pre-1980 housing on clay-rich ground is the most exposed; properties on bedrock or well-drained sandy soils are typically lower-risk. A postcode-level check picks up that variation.
A free postcode check on LocalRisk covers up to six hazards for any address in North Stoneham: Environment Agency flood mapping, BGS ground stability, Met Office heat projections, Defra PM2.5, plus coastal erosion and green-space access where relevant.
