According to the investigation data of Jiaozhou Bay in May, August and October of 1979, the vertical distribution and seasonal variation of water temperature at surface and bottom in inside and outside waters were studied, and the seasonal distribution, variation range and horizontal distribution trend were determined. The results showed that, in inside waters, bay mouth and outside waters, from May to August and to October, the seasonal variation was spring, autumn and spring, respectively, from high to low. It indicated that the water temperature was transported to everywhere in the ocean after the current transport in horizontal and vortex motion mixing in vertical direction. In terms of variation range, it was basically the same at surface and bottom in May, August and October. When it was low at surface, it was low at corresponding bottom; otherwise, it was opposite. From inside waters to bay mouth, the horizontal distribution of water temperature at surface was inconsistent with that at bottom in May, contrary in August and consistent in October. From bay mouth to outside waters, it was contrary in May, consistent in August and inconsistent in October. The horizontal distribution trend of water temperature disclosed that the source of high water temperature was the rising and decreasing heat.
