Understanding the UV Index is crucial for residents and visitors of Kahoeg, Sweden, where the climate is characterized by mild summers and a Cfb zone. As summer sunbeams become more intense, being aware of UV levels helps in preventing sunburn and protecting overall skin health. During peak hours, particularly from 11 AM to 2 PM when the UV Index reaches as high as 7, the risk of harmful effects escalates. By keeping track of these indices, locals can enjoy the beautiful outdoors while taking proactive measures against UV exposure.
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!
