The Great British Climate Quiz

Ten questions about Britain's climate, with every answer drawn from official UK data analysed across 1.8 million postcodes: Environment Agency NaFRA2 flood modelling, Met Office UKCP18 projections, British Geological Survey ground data, Defra UK-AIR air quality readings, NCERM coastal erosion mapping and ERA5 historical reanalysis.

Sample question: which has milder winter nights - the Outer Hebrides or Birmingham?

The Outer Hebrides, by a wide margin: 6.1°C average winter night temperatures against Birmingham's 2.9°C, despite sitting 500 miles further north. The Atlantic keeps the islands in mild maritime air all winter while inland England radiates its heat away under clear skies.

Sample question: which gets more hot days - Leeds or Brighton?

Leeds: 7.3 days above 25°C per year against Brighton's 4.7 (2023-2025). On the hottest days the sea cools coastal towns with onshore breezes while inland cities bake. Eight more questions like these - covering flood risk, subsidence, air quality, coastal erosion and how the 1976 heatwave compares with recent summers - are in the full quiz.
