Understanding the UV Index in Kalaheo, United States, is crucial for protecting your skin and overall health. With peak UV levels often reaching as high as 13, awareness can help prevent sunburns and long-term skin damage. Kalaheo's tropical climate means that the sun’s rays can be particularly intense, especially during midday hours. Knowing when to seek shade and apply sunscreen can make all the difference, ensuring you enjoy the beautiful outdoors safely. Keep an eye on the UV Index to stay informed and proactive against harmful UV exposure!
The UV Index today presents an interesting journey through the daytime hours. Starting from a gentle 1 at 07:00, the sun gradually intensifies, reaching a moderate 2 by 08:00. By 09:00, it's climbing rapidly, hitting 5 as the day warms up. Just after that, at 10:00, we see a significant leap to 8, before peaking at a staggering 12 at 12:00. The sun blazes on, reaching its zenith with a maximum of 13 at 13:00, providing plenty of reason to seek shade. As the afternoon progresses, the index starts to taper off, falling to 11 at 14:00, and then descending to 8 by 15:00. As the day winds down, the UV Index drops to 5 at 16:00, before settling back to 2 at 17:00 and eventually returning to a calm 1 by 18:00. As twilight sets in, the UV levels remain low at 1 until the end of the day at 19:00. It’s a perfect reminder to stay protected during the peak hours!

January and February also present significant risk, featuring very high UV Index values of 8 and 10, respectively. Visitors and residents should remain vigilant during these high-risk months by limiting sun exposure, wearing protective clothing, and applying sunscreen frequently.
