Understanding the UV Index is crucial for residents of Sanandaj, Iran, especially given its Dsa climate which can lead to high levels of ultraviolet radiation, particularly during the summer months. The UV Index provides essential information about sun exposure risks, helping you prevent sunburn, protect your skin health, and reduce the risk of long-term damage. With peak UV levels reaching an alarming 13 around midday, being aware of the daily UV forecast is vital for planning safe outdoor activities. Stay informed and enjoy the sun responsibly!
The UV Index reveals a dynamic fluctuation throughout the day, peaking dramatically at 1 PM with a soaring 13—a call for sun safety. Starting from a gentle 1 at 7 AM, the intensity gradually builds, reaching a moderate 5 by 9 AM. The sun's rays become more relentless, with a notable 10 at 11 AM and an even more intense 12 at noon. As the day progresses, the index begins to decline, dropping to 9 by 3 PM, and cooling to a casual 1 by 7 PM. Keep your sunscreen handy for peak hours when the UV exposure is at its highest!
