The sea-land breeze is a characteristic phenomenon of seaboard areas. Because the air temperature of the sea breeze is lower than that of the land breeze, the sea breeze can have a useful cooling effect during hot summers on the seaboard area. Statistics of wind and air temperatures in and around a seaboard city, Fukuoka, Japan, in summer are presented to describe the effects of the sea-land breeze on urban thermal environments. Statistical data for wind direction, wind speed and air temperature taken every 10 min on sea-land breeze days, i.e. days when both sea and land breezes appear, indicate that the sea breeze mitigates the rise in air temperature during the daytime. The time shift between land breeze and sea breeze is a dominant factor on fluctuations in air temperature of the area, and it depends on the distance from the coastline.
