The photo is from
a Sunday in June. Quite a few cars are present. There are camp sites
nearby and a hotel as well. The sea is calm on this day. It is however a
coast where caution is needed when bathing. Especially children need
well looked after. The habit of floating on a air mattress is not
recommended, especially not with offshore wind.
June is a good time to visit this area. Daylight until 2200 / 2300
hours, as you are a good deal North here.
