Data of long-term observations at three standard oceanographic sections are analyzed. A complex pattern of seasonal variability of oceanographic conditions off the southwestern coast of Sakhalin Island is studied. It is shown that the cold West Sakhalin Current directed to the south is observed from May to October; the low-salinity cold flow of the Sea of Okhotsk water oriented to the north is recorded from November to March. The northern boundary of penetration of the Sea of Okhotsk water is identified.
