Understanding the UV Index is crucial for the residents and visitors of Acre, Israel, where the Mediterranean climate brings hot summers and sunny days. Being aware of UV levels is essential for preventing sunburn and maintaining healthy skin, particularly during peak hours when the index rises significantly, reaching levels of 10 to 11 around midday. With typical exposure risks heightened, especially in a region known for its intense sun, it's important to stay informed and take protective measures. Whether you're strolling through Acre's historic streets or enjoying its beautiful beaches, knowing the UV Index can help you plan your day responsibly and safeguard your health.
At 07:00, the UV Index begins its climb with a modest level of 1. By 08:00, it doubles to 2, signaling the start of a gradual increase in solar intensity. As the sun rises higher, the index swiftly escalates to 4 by 09:00 and reaches a brisk 7 at 10:00. The peak occurs at 12:00, hitting a notable 10, and it continues to soar, reaching its maximum of 11 by 13:00. After this midday peak, the UV Index begins to decline, dropping to 9 at 14:00 and gradually decreasing to 7 by 15:00. As the afternoon progresses, it further retreats to 5 at 16:00 and falls to 3 by 17:00, finally settling back to 1 at 18:00 and 19:00. This prompts a reminder to take essential sun protection during the day, especially when the index is at its highest!

Throughout the year, UV exposure varies significantly, with the highest risk months occurring between April and August. The UV Index peaks in June and July at an extreme level of 11, allowing for a burn time of only 10 minutes. As summer approaches, particularly in May and June, caution is essential due to very high to extreme UV levels (UV Index 9-11). Visitors and residents are advised to take protective measures, such as wearing sunscreen, hats, and sunglasses, particularly during these months. Conversely, from November to March, the UV Index decreases to moderate levels, allowing for longer exposure times, but caution is still recommended, particularly in February and March when UV levels rise again. Overall, stay informed and protect your skin year-round, adjusting precautions as the UV Index changes.
