Understanding the UV Index is crucial for residents and visitors in Sarka Ghat, India, where the climate features a humid subtropical (Cwa) pattern that can elevate sun exposure. With UV levels reaching a maximum of 12 around noon, being aware of these fluctuations can be vital for preventing sunburn and protecting your long-term skin health. Knowledge of UV intensity not only helps you enjoy outdoor activities safely but also minimizes the risk of skin damage. As Sarka Ghat experiences significant UV exposure, especially between 10 AM and 2 PM, staying informed about the UV Index is your best defense against harmful effects of the sun.
The UV Index throughout the day reveals a striking pattern of intensity that peaks during midday hours. Starting at 07:00, the index begins at a low 2, gradually climbing to 4 by 08:00. As the sun rises higher, the index surges to 7 at 09:00 and hits a striking 10 at 10:00. The intensity reaches its zenith at 11:00 with an impressive 11, just before noon, peaking at 12 by 12:00—the most critical time for sun exposure. The afternoon sees a decline, dropping to 11 at 13:00 and then gradually easing to 9 by 14:00. By late afternoon, the index continues to fall, reaching 6 at 15:00, and dropping to 3 by 16:00. The evening brings a significant drop, as the index settles at 1 by 17:00, further decreasing to 0 by the end of the day at 19:00. This fluctuation emphasizes the importance of sun protection during the peak hours of 10:00 to 14:00.

Throughout the year, UV index levels show significant seasonal variation, with the highest risk occurring from March to August. During this period, particularly in April, May, July, and August, the UV Index reaches extreme levels of 11 to 12, necessitating urgent sun protection measures, as the burn time is dramatically reduced to just 10 minutes. Visitors and residents should take precautions such as wearing sunscreen, protective clothing, and hats, and seek shade, especially during midday hours. In contrast, the months of January, November, and December feature moderate UV levels (4 to 5), allowing for safer outdoor activities with longer burn times (30 minutes). February sees a shift to high risk (UV Index 6), indicating a need for more cautious sun exposure. It is essential to remain vigilant against UV exposure as the seasons change to ensure skin health throughout the year.
