In Krajan Krai, Indonesia, being aware of the UV Index is crucial for safeguarding your skin health and minimizing the risk of sunburn. Understanding UV levels helps residents and visitors alike to make informed decisions about sun exposure, especially during peak hours when the UV Index can soar to a maximum of 11 around noon. With its tropical Aw climate, Krajan Krai experiences intense sunlight, making it vital to protect yourself from harmful rays that can lead to long-term skin damage. Whether you're enjoying outdoor activities or simply soaking up the sun, being informed about UV exposure is your first line of defense against sun-related health issues.
The UV Index throughout the day presents a clear narrative of the sun's intensity. Starting at a gentle 1 at 07:00, the day quickly warms up, reaching 4 by 08:00. As the clock strikes 09:00, it escalates to 7, and by 10:00, it peaks at an intense 10. The intensity continues to surge, hitting a maximum of 11 from 11:00 to 12:00—a reminder to apply that sunscreen! Gradually, the index begins to decline, dropping to 9 at 13:00, and then diminishing to 6 by 14:00. From there, the UV levels swiftly taper off, resting at 3 by 15:00, and further declining to 1 by 16:00 and through 17:00. Finally, as the sun sets, the index cools off to 0 by 18:00, offering a soothing end to the day under the diminishing rays of light.
