As　China’s　urbanization　progresses,　the　urban　heat　island　(UHI)　effect　has　become　more　pronounced,　impacting　the　health　of　residents　and　the　activity　intentions　of　visitors　within　historic　urban　areas.　This　study　focuses　on　the　historic　district　of　the　Three　Lanes　and　Seven　Alleys　Tourist　Area　(SFQX)　in　Fuzhou,　where　simulations　were　conducted　on　four　representative　streets　across　various　times　during　a　typical　summer　meteorological　day.　Typological　methods　were　employed　to　simplify　neighborhood　modeling,　and　Phoenics　software　was　utilized　to　simulate　the　neighborhood’s　wind　environment　and　the　outdoor　pedestrian　thermal　comfort　index.　Aspect　ratio　(AR),　sky　view　factor　(SVF),　air　velocity　(Va),　and　universal　thermal　climate　index　(UTCI)　values　at　specific　locations　were　collected　for　statistical　analysis.　The　findings　reveal　that:　(1)　the　N–S　orientation　exhibits　more　significant　correlations　between　Va,　the　UTCI,　and　street　geometry　compared　to　the　E–W　orientation;　(2)　the　relationship　between　SVF　and　the　UTCI　fluctuates　with　time;　(3)　areas　with　higher　AR　values,　such　as　medium　and　deep　canyons,　offer　better　thermal　comfort　for　outdoor　pedestrians;　and　(4)　at　8:00,　the　UTCI　and　wind　speed　show　minimal　correlations　with　street　geometry　and　direction,　being　predominantly　influenced　by　objective　climatic　factors.　These　insights　are　expected　to　significantly　inform　the　geometric　design　and　planning　of　streets　in　Fuzhou’s　historic　districts,　aiming　to　create　more　comfortable　outdoor　environments　for　inhabitants　and　visitors　alike.　©　2025　by　the　authors.
