In Kalix, Sweden, being aware of the UV Index is essential for maintaining skin health and preventing sunburn, especially during the longer summer days when UV levels can rise significantly. Understanding these levels allows residents and visitors to make informed decisions about sun protection. With a Dfc climate, Kalix experiences unique challenges, including varied exposure risks during peak sunlight hours, typically between 11 AM and 3 PM when the UV Index can reach as high as 5.

The high-risk months of June and July see the UV Index peak at 6 and 5, respectively, where protection is paramount, and burn time drops to 25-30 minutes.

Ultimately, it’s advisable for everyone to stay vigilant and use sunscreen, wear protective clothing, and seek shade, especially during the spring and summer months when UV exposure is at its highest.
