In Portsoy, United Kingdom, awareness of the UV Index is crucial for maintaining skin health and preventing sunburn. With the Atlantic Ocean's influence, this coastal town experiences a mild Cfb climate, but that doesn't diminish the risks associated with UV exposure, especially during peak hours. Understanding the UV levels—which can reach a maximum of 7 during midday—empowers residents and visitors to make informed decisions when enjoying outdoor activities. By keeping an eye on the UV Index, you can protect your skin while basking in the beauty of Portsoy’s stunning landscapes.
As the sun rises, the UV Index (UVI) begins its ascent, starting with a mild level of 1 at 7:00 AM. By 9:00 AM, it reaches a level 3, indicating an increase in solar intensity. The real peak occurs at noon when the UVI hits a robust 7, representing the highest risk for harm from unprotected sun exposure. This high intensity persists until 3:00 PM, when it gradually recedes to a level of 6. As the afternoon wanes, the UVI dips further, dropping to 5 at 4 PM and finally back to a gentle 1 by 7 PM, allowing for a safe and comfortable evening. Remember, the hours between 10 AM and 3 PM mark the most crucial times for sun safety!
