In Qalyub, Egypt, staying aware of the UV Index is essential for safeguarding your skin against potential damage. Understanding UV levels is crucial for preventing sunburn, maintaining long-term skin health, and reducing the risk of skin cancer. The region's hot desert climate often exposes residents and visitors to intense sunlight, especially during midday hours, when the UV index can soar to 11—a level that signifies extreme risk. By keeping informed about UV levels throughout the day, you can better protect yourself and enjoy the sunny days in Qalyub while minimizing harmful effects.
The UV Index throughout the day presents a dynamic picture of sun exposure. As early as 7:00 AM, the index starts at a mild 2, ramping up to a moderate 4 by 8:00 AM. The sun's intensity peaks around 11:00 AM and 12:00 PM with a striking 11, marking the height of caution for outdoor activities. As we move into the afternoon, the index gradually declines, dropping to 8 by 2:00 PM and further to 5 by 3:00 PM. The evening brings relief, with the UV Index decreasing to a 1 by 5:00 PM and finally hitting 0 by 7:00 PM.
