Understanding the UV Index is crucial for residents and visitors in Clyde, New Zealand, as it plays a vital role in promoting skin health and preventing sunburn. Even under a Cfb climate, where temperatures remain moderate, UV radiation can pose risks, especially during midday hours when the index peaks at 2. By being aware of UV levels throughout the day, you can take proactive steps to protect your skin, ensuring your time outdoors in Clyde is both enjoyable and safe. Whether you're exploring the stunning scenery or enjoying outdoor activities, keeping an eye on the UV Index helps you stay protected from harmful rays.
The UV Index data reveals a gradual increase in sun intensity throughout the morning, starting from a safe 0 at 07:00 and 08:00. As the day progresses, the index reaches its peak of 2 during midday, specifically at 11:00, 12:00, 13:00, and 14:00—a time when sun protection is advisable. After this peak, the UV levels gently decline to 1 by 15:00 and remain steady until 17:00, before dropping back to 0 in the evening hours at 18:00 and 19:00. This data underscores the importance of being sun-smart during those peak hours!

Throughout the year, seasonal changes in the UV Index highlight periods of increased sun exposure risk. January and February** are high-risk months** with an extreme UV Index of 12-13, where a burn can occur in just 10 minutes. The intensity diminishes in March (UV Index 9) but remains very high, followed by a drop to high levels in April (UV Index 6). By May, the Index shifts to moderate (UV Index 3), offering some relief, and remains low during June and July (UV Index 2). However, caution is still advised as August and September see moderate UV levels (4-5). The risk resurfaces in October and November with very high indices (9-10), requiring caution once again for a burn within 15 minutes, and finally returns to extreme levels in December (UV Index 12). Visitors and residents should remain vigilant, especially during the high-risk months, and take protective measures such as sunscreen, clothing, and seeking shade during peak sun hours.
