The objective of this paper is to clarify the cooling effect of going-up sea breeze along the canal on thermal environment in the center of the city. Field observations of air temperature, humidity, wind direction and velocity were conducted in summer, 1994 and 1995 in Nagoya.These climatic conditions were measured at stationary points (the mouse of the canal and the center of the city), and moving observations points along the canal by car, around the canal on foot, and at the center of the city on foot. The sea breeze went up Horikawa canal up to 9〜11km in daytime in the maximum. In that case, the stronger the sea breeze blow, the lower the air temperature in the center of the city was. In case of the sea breeze went up not so far, the cooling effect of sea breeze appeared only around the mouse of the canal. The wind velocity on the canal as a whole were stronger than that in the street. In the center of the city, cooling spots appeared in the boulevard and the small park. As a result, two canals in Nagoya can act as "Wind trail" which introduces cooling air to urban hot climate.
