This study analyses the impact of Sky View Factor (SVF) on Outdoor Thermal Comfort using Heat Index and UTCI in Ahmedabad. The city was divided into 1 km grids based on MODIS night-time surface temperatures, with seven sites representing varied urban forms. Environmental parameters were measured four times daily over a month using standard instruments adhering to WMO guideline. SVF was calculated from fisheye images via Python. Results indicate both high and low SVF values correspond to high heat stress. Optimal comfort occurred near SVF 0.56, emphasizing the role of urban design in heat mitigation.
