Understanding the UV Index is crucial for residents of Neka, Iran, as it provides vital information about solar radiation levels and helps in preventing sunburn and maintaining skin health. With Neka's Csa climate, characterized by hot, dry summers, the potential for harmful UV exposure peaks significantly, particularly between late morning and early afternoon. For instance, during summer months, UV levels can reach as high as 11 at noon, indicating extreme risk for skin damage if precautions are not taken. By staying informed about the daily UV Index, residents can enjoy the sun safely and protect their skin from the harmful effects of overexposure.
The UV Index throughout the day demonstrates a significant rise as the sun reaches its zenith. Starting from a mild 1 at 07:00, the intensity escalates rapidly, hitting 3 by 08:00 and climbing to a peak of 11 at 12:00—the moment when sun protection is imperative. As the afternoon progresses, the index gradually declines, showing values of 10 at 13:00, 9 at 14:00, and 7 at 15:00. By 16:00, it drops to 4, and by the evening, the UV exposure wanes, returning to 1 by 18:00 and 19:00. This pattern underscores the importance of vigilance during midday hours when UV radiation poses the highest risk. Remember to stay shaded and apply sunscreen generously!

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. Visitors and residents should exercise caution and protective measures—especially between April and September—by wearing sunscreen, hats, and protective clothing, and seeking shade during peak daylight hours.
