Understanding the UV Index is crucial for residents of Bijar, Iran, especially given its characteristic Csa climate, which brings warm summers and a significant potential for sun exposure. Knowing the UV levels throughout the day can help you effectively prevent sunburn and protect your skin health. With maximum UV readings peaking at a staggering 13 around noon, the risks of overexposure increase significantly during peak hours, making it essential to stay informed and take appropriate precautions. Stay safe, enjoy the sun wisely, and safeguard your skin by checking the UV Index regularly!
The UV Index throughout the day experiences a striking progression, starting at a low level of 1 at 7:00 AM. As the sun climbs higher, the index rises sharply, reaching a notable 3 by 8:00 AM and then skyrocketing to 5 at 9:00 AM. The peak intensity arrives at 12:00 PM, where the UV Index hits an impressive 12, just before reaching its maximum at 1:00 PM with a 13. From there, it begins to decline gradually, slipping to 11 by 2:00 PM, 9 by 3:00 PM, and continuing to fall until it settles back to a 1 by 7:00 PM. This pattern highlights the importance of sun protection during midday hours when UV exposure is at its highest! Always remember to wear sunscreen and seek shade as needed!
