Town CLIMATE RISK
Cookstown is a town in Tyrone, within the Mid Ulster council area. LocalRisk has flood, heat, air and ground-stability data for 4,062 postcodes in Cookstown.
Met Office UKCP18 projections estimate around 5 days above 25°C per year across the Mid Ulster area for the 2021-2040 period - the central scenario under high emissions; lower-emissions paths give lower numbers. Heat exposure within Cookstown 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 5-day figure is an area average, not a property-level reading.
Annual mean PM2.5 across the Mid Ulster area is 4.1 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 Cookstown, 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 Cookstown 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.
