Time series observations, extending over two tidal cycles, of temperatures and micro‐temperature fluctuations at different positions and surface wave amplitudes at two fixed locations have been obtained in Esquimalt Lagoon (Esquimalt, B.C., Canada). The Lagoon is coupled to the sea by a narrow channel which permits about one‐third of the low tide water to be exchanged during a tidal cycle. A technique using drags and aerial photographs has enabled the water circulation to be measured. Temperatures measured two inches from the bottom exhibit remarkable stability (<0.1 °C fluctuation). No correlation between vertical temperature structure and surface waves or between micro‐temperature fluctuations and surface waves is observed.
