Integrating Objective and Subjective Thermal Comfort Assessments in Urban Park Design: A Case Study of Monteria, Colombia

Urban parks play a key role in mitigating heat stress and improving outdoor thermal comfort, especially in tropical and subtropical cities. This study evaluates thermal comfort in Nuevo Bosque Park (Montería, Colombia) through a multiperspective approach that combines perception surveys (n = 99), in situ microclimatic measurements, and spatial mapping. Surface temperatures ranged from 32.0 °C in the morning to 51.7 °C at midday in sun-exposed areas, while vegetated zones remained up to 10 °C cooler. Heat Index (HI) and Temperature–Humidity Index (THI) values confirmed severe thermal stress, with HI reaching 32 °C and THI peaking at 55.0 °C in some zones. Subjective responses showed that 69.69% of users reported thermal discomfort, especially in areas with impermeable surfaces and little shade. In contrast, 90.91% of respondents stated that tree cover improved their thermal experience. The results indicate a strong correlation between vegetation density, surface type, and users’ perceived comfort. Additionally, urban furniture location and natural ventilation emerged as key factors influencing thermal sensation. The integration of objective and subjective data has enabled the identification of microclimatic risk zones and informed evidence-based recommendations for climate-adaptive park design. This study offers practical insights for sustainable urban planning in tropical climates, demonstrating the importance of thermal comfort assessments that consider both human perception and environmental conditions to enhance the resilience and usability of public spaces.
