If you're fond of the sun, Hvide Sande is an excellent choice for a holiday destination. Its location by the sea means that here, as in Skagen and Bornholm, the sun shines for more hours each year than in the rest of Denmark.
In a normal Danish summer, you can see the clouds gathering inland when the western winds blow; here it will only rain for a short while as opposed to inland where it will rain cats and dogs. When the wind blows from the west and the north west, the sky is often blue and a light breeze streams down the coast in the middle of the day. That breeze usually settles in the evening.
At the height of summer, Hvide Sande and the surrounding area is generally the area with the highest temperatures in Denmark. Above 25 degrees centigrade is not unusual but it never gets too hot because the gentle breezes cool you in the middle of the day.
