Between buoys No 1-2 and buoy No 7 – 5-10 cm thick ice. Further westwards, from the buoy No 3, highly consolidated ice is observed with thickness of 20-35 cm. Ice compression is observed. Further westwards – clear water.
Between the port of Vyborg and the turning buoy of Vysotsk port: fast ice of 20-35 cm thick. The canal is free with 20-30 cm thick brash ice. Between the turning buoy of Vysotsk port and Vysotsk Gate (including water area of Vysotsk port) – solid ice with thickness of up to 30 cm. Between Vysotsk buoy and the Hally island – compact ice with thickness of up to 35 cm. Between the Hally island and buoy No 4 - consolidated ice with thickness of 15-25 cm. Between buoy No 4 and buoy No 3 – open pack ice.
From the port of Primorsk to buoys No 3-4 – dense ice of 20-30 cm thick, no movement on the canal. Further on, up to the Big Ship Fairway – 25-35 cm thick ice with concentration of 9-10/10ths with openings in some areas.
Between the port of Ust-Luga and Anchorage No 11 – new ice of 5-15 cm thick. Further, to the Anchorage No 10 (а) - open pack ice with ice free water in some areas. To the north of Anchorage No 10 (а) up to buoy No 9 - open pack ice.
