In Uttigen, Switzerland, being aware of the UV Index is essential for safeguarding your skin against harmful ultraviolet rays. Understanding the varying UV levels throughout the day can help prevent sunburn and promote long-term skin health, especially during peak hours when the risk is highest. With a Cfb climate, Uttigen enjoys a mix of temperate conditions, but the midday sun can easily push the UV Index to a striking 10—indicating intense exposure risk. Staying informed about these levels not only helps you plan your outdoor activities wisely but also encourages responsible sun protection practices for you and your loved ones.
As the sun rises, the UV Index begins to climb steadily throughout the morning, starting from a low of 1 at 07:00. By 09:00, it reaches 3, but the real surge occurs between 10:00 and 14:00, when it peaks at a remarkable 10. This indicates a high risk of harm from unprotected sun exposure. After 14:00, the intensity begins to wane, dipping to 8 at 15:00 and gradually decreasing to 3 by 18:00. As the day winds down, the UV Index falls back to a safe 1 by 19:00, reminding us of the importance of sun protection during those peak hours. Stay vigilant and protect yourself when the sun is at its strongest!
