Understanding the UV Index is crucial for residents of Kolumbug, Philippines, where the tropical climate can lead to significant sun exposure. With UV levels regularly peaking in the high to very high range, awareness of these levels is essential for preventing sunburn and protecting skin health. As you navigate the sun-soaked days, keep in mind that during midday hours—especially between 10 AM and 2 PM—the risk for harmful UV radiation rises sharply, making it imperative to take precautions and enjoy the beautiful weather safely.
The UV Index throughout the day reveals a clear pattern of intensity peaking around midday. Starting at a modest 2 at 7:00 AM, the index rises steadily, reaching a notable 11 by 10:00 AM. The highest reading, 14, occurs at 12:00 PM, indicating a significant risk for sun exposure. The intensity begins to decline post-lunch, dropping to 9 by 2:00 PM, and continues to decrease, falling to 5 at 3:00 PM. By evening, the UV Index plummets to 1 at 5:00 PM and settles at 0 by 6:00 PM. This pattern emphasizes the importance of sun protection during the midday hours when UV levels are at their peak.

Throughout the year, the UV Index remains alarmingly high, with values reaching as much as 17 in March, marking it as the peak month for potential harm from UV radiation. From January to September, the UV Index consistently falls within the extreme exposure category, making March, April, and September particularly high-risk months. Visitors and residents are strongly advised to take precautions during these months, limiting sun exposure to 10 minutes without suitable protection. It is essential to wear sunscreen, protective clothing, and seek shade during peak UV hours to minimize the risk of skin damage year-round. Remember, even in October and November, with UV Index values at 14 and 13 respectively, caution is still necessary as the sun remains fierce.
