The objective of this paper is to clarify the cooling effects of the sea breeze going-up along Shonai and Shinkawa rivers running around the outskirts of Nagoya on the urban thermal environment. In five days during summer of 2001 and 2002, air temperature, humidity, wind direction and velocity were observed as follows : these climatic conditions were measured at 4 stationary points and 58 mobile observation points along Shonai River, Shinkawa River, and some of streets crossing these rivers. The sea breeze from lse Bay went up these rivers in the daytime. ln that case, the cooling effects of the sea breeze were appeared over the area far about 15km from the sea. The wind direction of the sea breeze turned from southwest to southeast in the evening. Not only the wide rivers but also the narrow canal could acl as "Wind Trail" of the sea breeze over the area far from 5km at least. Heat island appeared clearly in the early morning of still fine days, but a part of heat island was cut off "Wind Trail" in the daytime. Consequently, both of Shonai and Shinkawa rivers were certified to have a role of "Wind Trail".
