Abstract<\/strong>. Cities are heating up faster than their rural counterparts due to the urban heat island phenomenon, with severe heat accumulation in various areas \u2013 hotspots. This study proposes a new approach to analysing urban heat islands by detecting and hierarchising their associated hotspots based on their severity derived from the combination of intensity and frequency. The new method, implemented in R, uses Landsat thermal band data, study area boundaries, and an imperviousness layer to pinpoint critical areas. It consists of a three-step process: i. identifying and prioritising hotspots for each usable satellite image; ii. computing the intensity and frequency, and iii. calculating severity and generating the maps. Combining reclassified multi-image intensity and persistence data, we derived nine classes representing the range from the most frequent and intense areas to the least. Incorporating the imperviousness layer, the hotspot extension is dramatically reduced. The resulting hotspot maps provide valuable insights for urban planners and policymakers, highlighting the most vulnerable regions within the urban area and signalling the need for targeted administrative interventions. This comprehensive analysis was also applied to cold spots, ensuring a thorough understanding of the most and least critical regions.<\/span><\/p>\n
