Recently, it has been desired to mitigate the Urban Heat Island Phenomena. So many studies have taken up the effects of sea breeze to mitigate the Urban Heat Island Phenomena. On the other hand, it is useful to clarify the effects of sea breeze for decreasing urban air temperature to consider the urban environmental design. In this paper, it is analyzed the effects of sea breeze based on the results of long-term multi-point measurements of air temperatures and observed wind conditions. As the results, the following were obtained. -The relations between sea breeze component velocity and air temperature at the measurement point near seashore were considered. As the results, it was clarified a rise of air temperature was decreased with increases of sea breeze component velocity. -The relations of distances from the near seashore, the arrival time of sea breeze on each point and sea breeze components velocity were analyzed. As the results, it was confirmed the relations between the arrival time of sea breeze on each point and sea breeze component velocity have high correlation. -The effects of sea breeze for decreasing urban air temperature were shown as a distribution map. As the results, the effects of sea breeze were clarified spatially and quantitatively.
