Daily Maximum Temperature

Welsh Government

Temperature patterns that can influence conditions within dwellings, and therefore the comfort and health of occupants, are projected to shift according to the Met Office Hadley centre climate models. To illustrate these patterns, the average daily maximum temperature(°C) is mapped for the average year in the time period for the 50th and 95th percentile models out of the 12-model suite. Time periods are baseline (1980-2000), 2030 (2021-2040), and 2070 (2061-2080). County-level results represent an area-weighted-average of the results for each climate data grid within the county.

Climate Projections consisting of Daily Maximum Temperature, Annual Precipitation, Daily Relative Humidity and Daily Specific Humidity

Indoor Conditions results consisting of Indoor Air Quality and Overheating

Building Fabric degradation results consisting of Solar Insolation, Precipitation and Relative Humidity 

Case Studies for four representative towns and cities illustrate results at a resolution of 2.2 km, giving insight into the variation that is projected geographically across each area:

Aberystwyth consisting of Climate, Indoor and Fabric

Cardiff consisting of Climate, Indoor and Fabric

Swansea consisting of Climate, Indoor and Fabric

Wrexham consisting of Climate, Indoor and Fabric
