Resumen

Amid escalating environmental pressures and the accelerating impacts of climate change, integrating climatological data into urban planning has become essential for sustainable city development. This study analyzes the spatial relationship between surface temperature patterns and key urban planning variables in Fortaleza, Ceará, Brazil. Landsat 8 satellite imagery from 2014 to 2022 was processed to generate temperature distribution maps, which were cross referenced with population density, land use and land cover, vegetation, water bodies, informal settlements, urban plot distribution, and vacant land. The results reveal a strong correlation between the reduction of natural cooling element — particularly vegetation and surface water—and the intensification of Urban Heat Island (UHI) effects. Areas undergoing rapid urbanization, especially coastal and high-density sectors, exhibited the highest thermal values, while zones with preserved green and blue infrastructure consistently maintained lower temperatures. These findings underscore the urgent need to incorporate urban climatology into land-use policies, zoning regulations, and environmental governance, ensuring that resilience and thermal comfort are integral to the planning and design of cities.
