This study is an attempt to reveal the microclimate on the loop and radial roads whose shape has been maintained since the early 20th century, in Hahoe, a traditional folk village in Korea, by field survey after confirming the characteristics of the regional climate. As the results show, the shape of the loop and radial roads which has earthen walls or the walls of earth and stones with an average height of 1.8 m on one or both sides, seemed to affect the winter microclimate in the loop and radial roads positively but the summer microclimate in some parts of the loop and radial roads were affected negatively. In addition, some parts of the loop and radial roads with a low ratio of wind velocity in summer seemed to have minimized adverse condition, because it is protected on both sides by the large crown of trees and earthen walls.
