In Khewra, Pakistan, understanding the UV Index is crucial for maintaining skin health and preventing sunburn. The UV Index serves as a valuable tool to help residents and visitors gauge the intensity of ultraviolet radiation on any given day, which is particularly important in Khewra's semi-arid climate (BSh), where UV exposure can be significantly high. Between the peak hours of 10:00 AM and 2:00 PM, the UV levels often soar to dangerous levels, reaching as high as 11. By staying informed about the UV Index, you can protect yourself from harmful effects of sun exposure, ensuring a safe and enjoyable experience under the sun.
As the sun rises, the UV Index starts at a mild 1 at 7:00 AM, perfect for early risers. By 8:00 AM, it increases to a moderate 3, hinting at the day ahead. Things heat up quickly, with the index peaking at an intense 11 around 12:00 PM, a reminder that sun protection is essential during midday. The UV levels maintain a strong presence, remaining at 10 at 1:00 PM before gradually tapering off to 9 by 2:00 PM. As the afternoon wanes, the UV Index drops to a cozy 6 at 3:00 PM and further descends to 4 by 4:00 PM. By the evening, the sun loses its intensity, with the index falling to 2 at 5:00 PM, and settling back to a safe 1 from 6:00 PM onward. This daily cycle underscores the importance of being sun smart, especially during peak hours!
