This study investigates the influence of scattered (irregular) and grid (regular) settlement layouts on local climate and thermal comfort versus rural open areas. Research in Erzurum, Türkiye, utilized 2022 year-round on-site measurements, satellite imagery, and statistical analysis of climatic parameters and the Physiologically Equivalent Temperature (PET) thermal comfort index. Findings reveal distinct climatic responses: scattered urban forms consistently created cooler conditions year-round, exhibiting a winter cold island effect (−1.8 °C in December) and lower summer air temperatures (−3.4 °C in July). According to land surface temperature (LST) results, the grid urban form (−12.1 °C) is 0.9 °C colder than the scattered urban form (−11.2 °C) in winter. The scattered urban form (27.9 °C) is 1.5 °C warmer than the grid urban form (26.4 °C) in summer. The grid urban form exhibits a wind velocity range from 0.2 m/s to 1.2 m/s, and the scattered urban form’s wind velocity ranges from 0.0 m/s to 0.5 m/s. On the other hand, PET analysis indicated scattered forms offered more favorable thermal comfort. Average PET for scattered forms was 16.6 °C in summer and −3.3 °C in winter, compared to grid forms’ 15.1 °C and −4.7 °C, respectively. Wind velocity was a primary determinant, with lower speeds reducing heat loss and improving comfort in cold regions. This highlights urban planning’s critical role in optimizing thermal comfort across climates.
