Understanding the UV Index is crucial for residents and visitors of Arvigo, Switzerland, where even a short exposure to the sun can lead to significant skin damage. The UV Index provides essential information on ultraviolet radiation levels, helping you take proactive steps to prevent sunburn and protect your skin health. In Arvigo's Dfc climate, where sunny days can unexpectedly escalate UV levels—peaking at 10 around midday—being informed about daily UV exposure risks is vital for enjoying outdoor activities safely. Stay educated and shield yourself from harmful rays to ensure a fun and healthy experience in this stunning Swiss locale.
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!
