As China’s urbanization progresses, the urban heat island (UHI) effect has become more pronounced, impacting health of residents and activity intentions visitors within historic areas. This study focuses on district Three Lanes Seven Alleys Tourist Area (SFQX) in Fuzhou, where simulations were conducted four representative streets across various times during a typical summer meteorological day. Typological methods employed to simplify neighborhood modeling, Phoenics software was utilized simulate neighborhood’s wind environment outdoor pedestrian thermal comfort index. Aspect ratio (AR), sky view factor (SVF), air velocity (Va), universal climate index (UTCI) values at specific locations collected for statistical analysis. The findings reveal that: (1) N–S orientation exhibits significant correlations between Va, UTCI, street geometry compared E–W orientation; (2) relationship SVF UTCI fluctuates with time; (3) areas higher AR values, such as medium deep canyons, offer better pedestrians; (4) 8:00, speed show minimal direction, being predominantly influenced by objective climatic factors. These insights are expected significantly inform geometric design planning Fuzhou’s districts, aiming create comfortable environments inhabitants alike.
