In Wailua, awareness of the UV Index is essential for protecting your skin and overall health. Understanding UV levels is crucial, especially as high exposure can lead to painful sunburns and long-term skin damage. With Wailua's tropical climate, residents and visitors alike face unique UV exposure risks, particularly during peak hours. For example, the UV Index soars to a critical level of 13 between noon and 1 PM, making sun safety measures vital. Stay informed and enjoy the sun responsibly!
The UV Index throughout the day presents a striking peak in intensity, making sun safety a priority. At 7:00 AM, the day starts off gently with a low index of 1, increasing to 2 by 8:00 AM. As the sun climbs higher, the index soars to 8 by 10:00 AM and hits its maximum at 12:00 PM with a blistering 13. This high level persists into the early afternoon, remaining at 13 until 1:00 PM, before beginning a gradual decline. By 3:00 PM, it drops back to 8, and by the late afternoon, the risk diminishes to 2 at 5:00 PM. Finally, as the sun sets, the index returns to a comfortable 1 by 6:00 PM, emphasizing the importance of taking precautions during the peak hours to protect your skin.

From January to December, the UV Index rises dramatically, reaching an extreme level of 13 from May to August, making these high-risk months for sun exposure. During this period, the recommended burn time drops to just 10 minutes, indicating the urgent need for protection such as sunscreen and clothing. February and March also present heightened danger, categorized as very high and extreme, respectively, where the burn time sharply decreases.
