In Haddington, United Kingdom, being aware of the UV Index is vital for protecting your skin and overall health. Understanding the daily UV levels helps residents prevent sunburn and reduce long-term skin damage, especially during peak hours when the UV index reaches a high of 7 from 12 PM to 2 PM. With Haddington's Cfb climate—characterized by cool, temperate weather and frequent overcast skies—many may underestimate their sun exposure. However, even on cloudy days, ultraviolet rays can penetrate through the clouds, making it essential to stay informed and take protective measures to enjoy the outdoors safely.
As the day unfolds, the UV Index begins at a modest 1 at 7:00 AM, indicating low sun exposure. By 9:00 AM, it rises to a 3, signaling a gentle increase in UV rays. The sun reaches its peak intensity around noon, with the index hitting 7—a reminder to stay protected. From 12:00 PM to 2:00 PM, the index holds steady at this elevated level, ideal for sun safety measures. As the afternoon progresses, the UV Index gradually declines: 6 at 3:00 PM, then tapering to 2 by 6:00 PM, and finally back to 1 by 7:00 PM. It’s a clear reminder that while the sun’s power peaks early in the day, it’s essential to stay aware of UV exposure throughout.

Throughout the year, UV Index levels show significant seasonal variation, with high-risk months typically occurring from May to August. In June, the UV Index peaks at 8, indicating a very high risk of harm from unprotected sun exposure, with a burn time reduced to just 15 minutes. Conversely, from January to February and again in November to December, the UV Index remains low (1-2), allowing for longer exposure times (up to 45 minutes) without significant risk. As such, for residents and visitors, it is strongly advised to take protective measures during the high UV months, particularly from May to July, which includes wearing sunscreen, protective clothing, and limiting sun exposure during peak hours. During the winter months, while the risk is lower, it's still wise to remain cautious as UV rays can still cause skin damage.
