In this research, the characteristic of air temperature distribution in summer was considered based on air temperature data observed for three years in Osaka city. Although the average air temperature had transition, the relationship between every observation points was same for three years. The influence of the sea breeze is dominant to daytime air temperature, from around 10:00 when the sea berrze begins to blow to around 19:00 when the sea breeze becomes weaker. The influence of the land use around the observation points is dominant to nighttime air temperature. High correlation between the ratio of natural covering (green, bare, water surface) and nighttime air temperature was accepted.
