Northern Ireland Rural Heat Map

As part of the Once Upon a Time in a Heatwave project, an online app for mapping summer heat risk has been created for use by Northern Irish rural communities and decision makers to understand where and by how much summer temperatures may increase. Using data from the Met Office’s UK Climate Projections 2018, a number of different graphics can be produced. These include downloadable maps of hot summer temperatures – showing where these exceed certain levels or ‘thresholds’ – and graphs showing how the number of hot days and nights will change in the future for a given postcode in Northern Ireland. Temperature thresholds can be adjusted by the user, so graphics can be compared to other products such as the Met Office’s Belfast Heat Pack, which gives several examples of how infrastructure and health can be impacted above certain temperatures.
