Understanding the UV Index is crucial for residents and visitors of Passi, Senegal, where the sun shines brightly, especially during peak hours. With a climate classified as BSh, the UV levels can soar to dangerous heights, reaching up to 12 during midday. Awareness of these levels is essential for preventing sunburn and protecting your skin health. By staying informed about daily UV fluctuations, you can take necessary precautions to enjoy the sun safely while minimizing the risks associated with prolonged exposure.
As the sun rises, the UV Index begins its steady ascent, peaking dramatically during the midday hours. At 07:00 and 08:00, it lingers at a safe 1, making sunscreen unnecessary. However, come 09:00, the index jumps to 3, signaling growing sun intensity. The real surge occurs between 10:00 and 14:00, where the UV Index escalates to a sharp 12 at 13:00—a reminder to seek shade and protect your skin. As the afternoon rolls in, a gradual decline starts, dropping to 6 by 16:00 and returning to a mild 1 by 19:00. This hourly dance of UV levels underscores the need for vigilance during the sun's most potent hours.
