Field measurements of outdoor wind and thermal environments were carried out in the summer in Haramachi City of Fukusima Prefecture for two years. The aim of this study is to investigate the present outdoor thermal environment condition of urban area in such provincial cities and the factors, that is land and sea breeze and land cover, contributing to air temperature increasing and decreasing. In the first year, the measurements obtained for cold northeast wind, "Yamase", and air temperature showed that the records were not so high. Water temperatures from river and sea were also measured, and the readings both showed higher than air temperature in surroundings. Air temperatures measured from the river area showed cooler than around residential and urban areas. This is because river played an important role as a passage of cold air from the sea. Long-term measurement was carried out and the data in typical fine day in summer were obtained in the next year. It was confirmed that air temperature in and around the city was decreased when sea breeze blew. On the other hand, the tendency that air temperature was high in the period where land breeze blew was seen.
