Understanding the UV Index is crucial for residents of Seaham, United Kingdom, where the coastal climate brings a unique set of sun exposure challenges. With UV levels rising throughout the day—reaching a peak of 8 by 1 PM—being aware of these fluctuations is essential for preventing sunburn and protecting your skin health. Given Seaham's temperate maritime climate, even on overcast days, harmful UV rays can still penetrate the clouds, making it imperative to know when to stay covered or seek shade. Embracing UV Index awareness not only helps you enjoy the outdoors safely but also supports long-term skin health and well-being.

Be mindful of the sun’s powerful reach, especially during its peak hours!
