In Derna, Romania, staying informed about the UV Index is crucial for maintaining skin health and preventing sunburn. With the region's temperate oceanic climate (Cfb), residents and visitors alike are exposed to varying UV levels, especially during the peak hours between 11:00 AM and 3:00 PM, when the index can soar to 9—a high risk for skin damage. Understanding these UV levels not only helps in planning outdoor activities but also fosters a culture of sun safety, allowing everyone to enjoy the beautiful weather while protecting their skin. Always check the UV Index to make informed decisions and safeguard your well-being under the sun!
As the sun rises, the UV Index gradually climbs, starting at a low of 1 by 07:00 and 08:00. The real leap begins at 09:00, where it reaches 3, escalating to 4 by 10:00. As noon approaches, the UV Index peaks at an impressive 9 from 13:00 to 14:00, making it crucial to take protective measures during those hours. Afterward, it begins to taper off, dropping to 6 by 16:00, and further declining through the late afternoon and evening, eventually falling back to 1 by 19:00. For those venturing outdoors, staying vigilant to the UV levels during the midday hours is essential for skin protection!

As the seasons change, so does the UV Index, which is crucial for understanding sun exposure risks. From January to February, the UV Index starts low at 2, indicating a minimal risk of harm, but it gradually rises to 3 in February, marking a moderate exposure category with a burn time of 30 minutes. The risk intensifies significantly from March to August, peaking at 9 during June and July, where the burn time reduces to just 15 minutes under very high risk.
