Parts of the east coast is rough when the wind is from the west, for example Clifford Bay. I think the wind must sweep around the white bluffs… Sometimes even Cape Cambell south to Kekerengu is unpleasant during a strong NW with the wind hitting from the side. Cloudy Bay is pleasant enough, with the wind hitting from behind.. So normally pleasant when the wind is from the W/NW. NW is certainly one of the best forecasts for Kaikoura, normally very calm. But my knowledge is lacking for anything south of Oaro.
