Understanding the UV Index in Ullubiyaul is crucial for maintaining skin health and preventing sunburn, especially during the peak hours of daily sun exposure. The city, located in a Dfa climate zone, often experiences high ultraviolet radiation levels, particularly from late morning to early afternoon, when the UV Index can soar to a maximum of 10. By being aware of these UV levels, residents can take necessary precautions to protect their skin and enjoy outdoor activities safely throughout the year. Stay informed and shield yourself from the sun’s harmful effects!
The UV Index peaks dramatically during the midday hours, highlighting the importance of sun safety. Starting at a mild 2 at 07:00, the index climbs steadily, reaching a moderate 4 by 08:00. By 10:00, the sun’s intensity escalates to 9, and at 11:00 and 12:00, it hits a scorching 10, signaling a high risk for unprotected skin. As the afternoon progresses, the index begins to decline, dropping to 9 at 13:00, and tapering to 5 by 15:00. The later hours see a gentle decrease, with the UV level falling to 3 at 16:00, then further to 2 by 17:00 and a minimal 1 from 18:00 to 19:00. This data emphasizes the critical window for protective measures against UV exposure, especially between 10 AM and 2 PM.

Throughout the year, the UV Index fluctuates significantly, indicating varying levels of risk for sun exposure. From January to February, UV levels remain in the moderate range (3-4), allowing for approximately 30 minutes of safe sun exposure. As spring approaches in March, the UV Index escalates to 7, marking the beginning of high risk, with a reduced safe exposure time of 25 minutes. The late spring and summer months, particularly April to August, experience the highest UV readings, with values reaching a peak of 10 in June and July, categorizing them as very high risk and necessitating careful sun protection after just 15 minutes of exposure. September sees a slight decline to an 8, while October drops to a 6, signaling a return to high risk. Conversely, late fall and winter months—November (3) and December (2)—see safer exposure categories, with burn times extending up to 30-45 minutes. Visitors and residents should take proactive measures in high-risk months (March to September) by using sunscreen, wearing protective clothing, and seeking shade to minimize sun damage.
