UV index in Ilulissat

Ilulissat lies at 69°N. The midday sun reaches 14.9° above the horizon in Ilulissat today, against a yearly ceiling of 44.2°. Elevation is what sets the ceiling for UV, and over Ilulissat it is low even at midsummer, though snow can reflect UV and add to the exposure in spring.

What is the UV index?

The UV index is an international scale describing the strength of the sun's ultraviolet radiation at ground level. It starts at 0 and is effectively open-ended — at mid-latitudes it rarely exceeds 8, while in the tropics and high in the mountains it can pass 11. The higher the number, the less time it takes to get sunburnt.

The UV index depends mainly on how high the sun is in the sky. That is why it peaks around solar noon and is greatest in summer near the longest day of the year. Clouds, ozone, altitude and reflection from snow or water also affect the value.

The WHO UV scale

UV index	Level	Recommendation
0–2	Low	No special protection needed.
3–5	Moderate	Use sunscreen (SPF 30+), seek shade around midday.
6–7	High	Sunscreen, hat and sunglasses. Avoid the sun 12:00–15:00.
8–10	Very high	Extra protection. Limit midday sun exposure.
11+	Extreme	Avoid the sun at midday. Full protection required.
