Just how hot and dry was your summer? Use our postcode lookup to find out

The UK faced its hottest summer on record this year, with much of the country experiencing drought and repeated heatwaves. But temperatures and rainfall were not the same everywhere. Type in your postcode to summer 2026 was like in your area. Data up to August 2026 This lookup uses data from the HadUK Grid dataset (opens in new tab), which is produced . HadUK Grid is one of the main products used ’s changing climate. The HadUK dataset displays temperature and rainfall data across a uniform grid covering the entire landmass of the UK. The data does not cover the Channel Islands. Every value on the grid is an estimate for the centre point of a 1km by 1km grid box, the most detailed climate data publicly available for the UK. The values are created using observations from land-based weather stations across the country, and , terrain and distance from the coast to scientifically “fill in the gaps” between weather stations. The results displayed for each grid area represents a mean average of that grid cell and its nearest grid cells. For most areas, this represents a 5km square centred on the primary grid cell. Along irregular coastlines and on small islands, the nearest grid cells are chosen to match the shape of the coastline or island, but no cells are further than 7km away. This approach aims to avoid sharp jumps between neighbouring locations which may occasionally arise due to uncertainties in the data, while still making use of the most detailed dataset available to capture local weather conditions across the UK's varied geography. The data for 2026 is provisional, with fewer observations feeding into calculations due to lags in data availability. As such, the precise values could change slightly in future as more data comes available. The historical averages are calculated over a 30-year period from 1991-2020, which matches the standard period used ’s World Meteorological Organization. The average temperature represents the mean average of the selection of grid cells across the month or season. The maximum temperature is the mean average of the daily maximums recorded across all nearest grid cells for the month or season; the minimum temperature is the mean average of the daily minimums. The rainfall is the total amount of rain for the month or season, averaged across the selection of grid cells. Methodology support from Dan Hollis, Amy Doherty and Oli Claydon, UK Met Office.
