In Juybar, Iran, being aware of the UV Index is crucial for safeguarding your skin and overall health. With UV levels peaking around noon—reaching a maximum of 10—understanding these fluctuations can help you prevent sunburn and long-term skin damage. This region's Mediterranean climate not only brings warm summers but also increases exposure risks during the hottest hours. Staying informed about the UV Index allows residents and visitors alike to enjoy the sun safely while protecting their skin health.
The UV Index throughout the day showcases a distinct rise and fall, reflecting the sun's intensity. Starting at a gentle 1 at 07:00, the index progressively climbs, hitting 2 by 08:00. As the day warms up, it reaches 4 at 09:00, surging to a peak of 10 by 12:00 and staying steady until 13:00. After peaking, the UV intensity begins to wane, dropping to 8 by 14:00, and continuing its descent to 6 at 15:00, before tapering off to 4 at 16:00, and finally returning to 1 by 18:00 and 19:00. This dynamic pattern highlights the importance of sun safety during peak hours, particularly from 11:00 to 13:00 when the UV Index is at its highest.

The UV Index exhibits notable seasonal changes, peaking during the summer months. January and February see moderate UV exposure with values of 3 and 4, allowing for a burn time of 30 minutes. However, starting in March, the risk escalates sharply with a UV Index of 7 (high), and by April, it reaches 8 (very high), reducing burn time to 15 minutes. The dangerous period peaks in May with an extreme UV Index of 11, signaling only 10 minutes of safe exposure. June and July maintain high UV intensity (10), while August and September remain very high (9 and 8, respectively), again enforcing a 15-minute burn time. As fall approaches, October sees a drop to 6 (high), extending burn time to 25 minutes, and November and December revert to moderate levels of 4 and 3, allowing for 30 minutes of exposure.
