In Macachacra, Peru, understanding the UV Index is essential for safeguarding your skin and overall health. With the region's BSk climate often exposing residents and visitors to heightened UV levels, awareness of daily fluctuations in UV intensity can help prevent sunburn and long-term skin damage. Notably, during peak hours from 11 AM to 1 PM, the UV Index reaches a maximum of 13, indicating a very high risk for harm without proper protection. Staying informed about UV levels allows you to enjoy the beautiful outdoors while effectively shielding yourself from the sun's harmful rays.
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.
