In Marsa, Malta, being aware of the UV Index is essential for safeguarding your skin against harmful ultraviolet rays. Understanding UV levels not only aids in preventing painful sunburns but also plays a vital role in long-term skin health. With a Mediterranean climate that brings warm summers and abundant sunshine, Marsa typically presents substantial UV exposure risks, especially during peak hours between 11:00 AM and 2:00 PM, when the UV Index can soar to 11. Stay informed and protect yourself as you enjoy the beautiful sunshine!
As the sun rises, the UV Index begins at a mild 1 at 07:00, gradually escalating throughout the morning. By 10:00, it peaks at a robust 6, and then skyrockets to its maximum of 11 by 13:00—a time when protective measures become essential. The intensity starts to wane in the afternoon, dropping to 8 at 15:00, and further retreating to a gentle 1 by evening. It's a classic case of the sun's power, reminding us to stay vigilant and shield ourselves during those peak hours!
