How high is the UV index in Denmark in summer?
Moderate to high in the summer months
Short answer
In Denmark the UV index peaks at about 7 in the summer months, which is in the high band (6–8). From April to September it is usually above 3 between 12.00 and 15.00. The advice is to protect yourself from the sun when the UV index is 3 or higher. You can get sunburnt even when it is cloudy, and you can follow the UV index on dmi.dk.
Why
- Long summer days mean many hours of sun.
- UV is strongest between 12.00 and 15.00.
- You can burn even under cloud.
Details
Below 3 the risk of sunburn is low, 3–6 is moderate, 6–8 high, 8–10 very high and above 10 extreme.
Tip
Look up the UV index on dmi.dk before a beach or bike day.
What may differ
Outside the hours 12.00 to 15.00 and outside April to September the UV index is usually lower.
Common misconception
The sun in Denmark is too weak to burn you.
What actually happens
A UV index of up to about 7 in summer means a high risk of sunburn without protection.
