Understanding the UV Index is crucial for residents and visitors of Bandar-e Deylam, Iran, where the sun's intensity can pose significant health risks. With the region's BWh climate, characterized by hot and arid conditions, knowing the daily UV levels helps in effectively preventing sunburn and maintaining skin health. Peak UV values, such as a dangerous level of 12 at noon, highlight the importance of taking protective measures outdoors. By staying informed about UV exposure, you can enjoy the beautiful Iranian sun while safeguarding your skin against its harmful effects.

The peak intensity occurs around 12:00, where it hits a blistering 12, categorizing the risk as extreme. Thankfully, as the sun begins its descent, the UVI dips back down to 10 at 14:00, and continues to decline, hitting 4 by 16:00. As evening approaches, the index settles at 1 by 19:00, indicating a safe window for evening activities. Prepare wisely, especially during the midday hours!
