Met Office UKCP18 projections (50th percentile) estimate around 3 days above 25°C per year for the area covering BT30, averaged over the 2021-2040 period under the RCP8.5 high emissions scenario. These are probabilistic projections - the full range of modelled outcomes is wide and lower emissions scenarios would produce lower figures.
Annual mean PM2.5 for the council area covering BT30 is 4.3 µg/m³ - close to the World Health Organisation guideline of 5 µg/m³. Postcodes within 200 metres of an A-road or major junction routinely run higher during weekday rush hours than residential streets two roads back.
Ground stability in BT30 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. A postcode-level check picks up that variation.
