In Sillapata, Peru, being aware of the UV Index is crucial for maintaining skin health and preventing sunburn. With the region's cool oceanic climate (Cfb), you might not expect high UV levels, yet the data reveals peak indices reaching 13 between noon and early afternoon. Understanding these UV levels not only helps you protect your skin but also ensures you enjoy outdoor activities safely. As the sun rises and angles change, so does risk, making it essential to stay informed about daily UV exposure in this unique locale.
As the sun rises, the UV Index begins at a low 1 at 07:00, gradually climbing to reach 2 by 08:00. The intensity ramps up significantly as the day progresses, peaking at a striking 13 at 12:00. The sun's rays hit their maximum power between 11:00 and 13:00, with a 12 at 11:00 and lingering at 13 until 12:00. After that, the UV Index starts to decline, dipping to 9 by 14:00 and further down to 5 by 15:00. As evening approaches, the index falls to 2 at 16:00, then returns to a safe 1 at 17:00 before wrapping up the day with a zero reading by 18:00. This pattern underscores the importance of sun safety during those peak hours when the UV Index is highest.
