The GT Harbour will experience NW winds 5 to 10 knots on Tuesday morning Dec 3, 2019, switching to North Northeasterly in the afternoon. Seas in the afternoon will be 3ft from the NW, going down to 2ft as the front moves away. The NW swells will likely impact the harbour from Tuesday afternoon until Wednesday morning and then dissipate. Small craft along the west coast and those on moorings should take extra precautions.
