In Mulleriyawa, Sri Lanka, awareness of the UV Index is crucial for safeguarding your skin and overall health. Understanding the daily UV levels can help you prevent sunburn and reduce long-term skin damage. With a tropical climate characterized by intense sun exposure, residents and visitors alike must be vigilant, especially during peak UV hours from 10 AM to 1 PM, when values soar to a maximum of 12. By staying informed about UV intensity, you can effectively enjoy the outdoors while minimizing health risks linked to UV radiation.
The UV Index data reveals a dynamic progression throughout the day, with the sun's intensity gradually rising from a modest 2 at 07:00 to a peak of 12 during both 11:00 and 12:00. This indicates a high risk for sun exposure, making it crucial to take protective measures. As the afternoon rolls in, the index declines, gently tapering off to 8 by 14:00, before plummeting to a mere 1 at 17:00 and hitting 0 by 19:00. Thus, for sun lovers and outdoor enthusiasts, the midday hours (10:00-14:00) are the golden time to enjoy the outdoors, while the diminishing levels later offer a safer reprieve. Remember to stay safe under the sun!
