Based on water exchange, the horizontal and vertical variation of water temperature heat were proposed by the author, and their definitions and equations were determined in this paper. According to the water temperature of Jiaozhou Bay in May, August and October of 1979, the horizontal and vertical variation of water temperature heat at surface and bottom were calculated. Besides, the corresponding diagrams were obtained. The horizontal variation showed that in May, August and October, from inside waters to bay mouth, then to outside waters, the horizontal decrease amount of water temperature heat reached 0.05-0.82% at surface and 0.00-7.62% at bottom, less than 1.00%. Even in the hottest season, it was less than 12.00%. Hence, spatially and temporally, when waters exchanged at surface and bottom, the heat loss was low. In this way, the heat could be transported for long distance. The vertical variation showed that in inside waters, the vertical decrease amount at surface and bottom reached 13.27% in summer, but 2.47-3.45% in spring and autumn. Whereas, in bay mouth, it reached 13.59% in summer and 1.66% in spring. It became vertical increase amount of 0.05% in autumn. In outside waters, from spring to summer, further to autumn, the vertical decrease amount decreased from 9.91% to 6.32%, further to 0.00%, respectively.
