Understanding the UV Index is essential for residents of Hiranagar, India, where the sun can be particularly intense. With UV levels peaking at 10 during midday hours, awareness is crucial for preventing sunburns and protecting overall skin health. Hiranagar's climate, characterized by hot summers and ample sunshine, increases the risk of UV exposure, making it vital to stay informed. By monitoring the UV Index, you can take proactive steps to shield yourself from harmful rays and enjoy the outdoors safely.
At sunrise, the UV Index starts at a gentle 2 at 7:00 AM, gradually climbing to a moderate 4 by 8:00 AM. As the day progresses, the sun's intensity peaks with a striking 10 at both 11:00 AM and 12:00 PM, indicating a high risk of harm from unprotected sun exposure. By 1:00 PM, the index remains strong at 9, but starts to decline to 7 by 2:00 PM. Early afternoon light gives way to a safer environment as the index sinks to 5 at 3:00 PM, then further drops to 3 by 4:00 PM. As the sun sets, the UV Index descends into the low range, resting at 1 by 5:00 PM and tapering off to 0 after 7:00 PM—a clear reminder to protect your skin during those peak sun hours!

Throughout the year, UV levels vary significantly, with the highest risks occurring during the spring and summer months. March to August marks a period of very high to extreme UV exposure, with May and July seeing the peak UV Index of 11 and 12, respectively, where the burn time drops to just 10 minutes. During these months, it is crucial for visitors and residents to take protective measures, such as wearing sunscreen, sunglasses, and protective clothing, particularly during midday hours. April and June also exhibit very high levels, with burn times of only 15 minutes. Transitioning into September and October, the UV Index decreases but remains high enough to warrant caution, with a burn time of 25 minutes in October. The high-risk months are therefore from March through August, requiring extra vigilance to avoid harmful effects of sun exposure. As the UV Index returns to moderate levels in November and December, precautions remain advisable during peak sun hours.
