In Cogo, Equatorial Guinea, awareness of the UV Index is crucial for protecting your skin from harmful ultraviolet radiation. Understanding UV levels helps you take preventative measures against sunburn and long-term skin damage, which is especially important in this tropical climate where UV exposure can be intense. With peaks often reaching 10, particularly during midday, residents and visitors should stay informed to enjoy the sun safely while safeguarding their skin health. Whether you’re planning a day outdoors or simply enjoying your surroundings, knowing the UV Index can make a significant difference in your daily sun protection routine.
The UV Index throughout the day follows an illuminating path, beginning with a gentle maximum of 1 at 7:00 AM. As the sun rises higher, the index climbs steadily, reaching a comfortable 2 by 8:00 AM. By 9:00 AM, it hits 4, but the real intensity begins at 10:00 AM when it surges to 7. The peak arrives at 12:00 PM and 1:00 PM, both clocking in at a strong 10, urging sun seekers to adopt protective measures. The afternoon sees a gradual decline, dipping to 8 at 2:00 PM, then to 5 by 3:00 PM. As the sun begins its descent, the index falls further to 3 at 4:00 PM, before retreating back to 1 by 5:00 PM, and finally settling at 0 by 7:00 PM, marking the end of a day under the sun's potent rays.
