In Semenov, understanding the UV Index is crucial for safeguarding your skin and overall health against the sun's harmful rays. With typical peak levels reaching 6 around midday, being aware of UV exposure can help you prevent sunburn and long-term skin damage. Semenov's Dfb climate features warm summers, making it essential to monitor UV levels, especially during peak sunlight hours between 10:00 AM and 2:00 PM. Protect yourself and enjoy the sunshine safely by staying informed about the daily UV Index!
The UV Index throughout the day peeks with intensity as the sun ascends and then gracefully descends. Starting at 2 at 07:00, the index escalates to 6 by 11:00, maintaining that level until 13:00—the peak time for sun exposure! As the afternoon progresses, the UVI gently drops to 5 at 14:00 and continues to descend to 4 by 15:00. The late afternoon and evening hours offer a welcome relief with UV levels decreasing to 2 by 17:00, and finally tapering off to 1 by 19:00.

Throughout the year, the UV Index exhibits notable seasonal changes, with high-risk months typically occurring from June to August when levels reach 6 or higher, indicating a high exposure risk and a reduced burn time of just 25 minutes. In contrast, the winter months of January, November, and December experience a low UV Index of 1, where individuals can safely spend up to 45 minutes in the sun without significant risk of sunburn. As spring approaches, the UV Index gradually rises, peaking in April and May at a moderate 5, which necessitates a bit more caution, allowing only 30 minutes of unprotected sun exposure. To ensure safety, visitors and residents are advised to be particularly vigilant during the summer months, using adequate sun protection techniques such as sunscreen, protective clothing, and seeking shade during peak sunlight hours.
