Experimental investigations of the wave processes performed in the coastal zone near the settlement Vzmorye Sakhalin Isl.) allowed obtaining a digital record of a rare occurrence extreme negative surge observed during cyclone passage over the northern part of the island. The analysis of the meteorological conditions of the negative surge and its spectral characteristics was performed. The dynamics of the wind waves and swell was considered. It was discovered that in the process of the negative surge there was a significant decrease of the wave amplitudes until the end of the negative surge period, after which even a noticeable rise was recorded.
