The purpose of this research is to better understand the link between urban heat and cool island, as well as the Local Climatic Zones (LCZ) existing in the city of Balneário Camboriú, Southern Brazil, based on the atmospheric systems functioning on the dates investigated during the winter season. To gather data on environmental factors, 11 permanent locations in the Balneário Camboriú metropolitan region were chosen. To understand the atmospheric systems operating in the region, a synoptic analysis of the dates was performed, and thus, the LCZs map created for the city in World Urban Database and Acess Portal Tools was used to correlate the magnitudes of the heat and cool islands found for Balneário Camboriú in the winter period and the LCZs found by Hoppe et al. (2022) in the study area. The findings indicate that LCZs with sparsely distributed buildings (LCZs 6, 8 and 9) and LCZs with dense vegetation (LCZ A) have lower intensity magnitudes of heat and cool conditions. The biggest magnitudes of heat and cool islands were reported in LCZs 1 and 3 during the timeframe. This study’s synoptic analysis supports earlier researches that points to atmospheric stability (Anticyclonic domain) as a favorable atmospheric setting for the emergence of urban hear and coolness islands.
