Understanding the UV Index is crucial for residents of Canchungo, Guinea-Bissau, as it helps guide sun safety and protect skin health. With UV levels soaring to a peak of 12 during the midday hours, awareness of these fluctuations is vital for preventing sunburns and long-term skin damage. The local Aw climate brings warm weather year-round, but also increases the risk of harmful UV exposure, particularly in the intense sunlight between 11:00 AM and 2:00 PM. Staying informed about the UV Index allows you to enjoy outdoor activities safely while minimizing health risks.
As the sun rises, the UV Index begins at a minimal level of 1 at 7:00 AM and gradually climbs throughout the morning. By 10:00 AM, it reaches 6, and by 11:00 AM, it spikes to a significant 9. The peak arrives at 12:00 PM and 1:00 PM, where the UV Index hits a striking 12, indicating the highest potential for skin damage. The intensity starts to wane by 2:00 PM, dropping to 11, and gradually decreases to 9 at 3:00 PM. As the evening approaches, the index continues its decline, with levels returning to 3 by 5:00 PM before settling back down to 1 by 7:00 PM. It’s essential to stay protected during those midday hours when UV exposure is at its peak!
