We went to this beach yesterday for a Sunday's stroll. My hubby and his friends also swam in the sea. It was about 6 degree in the water, but warm and nice in the land.
Here is a small bay with sandy beach and shallow water. Perfect for family with small children and others that just want to wade in the water.
Viste Strand Hotel (Viste Beach Hotel) is located just North of Stavanger on the Western seashore. It has a very nice sandy beach just down from the hotel.
