In San Miguel Amatitlán, Mexico, staying informed about the UV Index is essential for protecting your skin and overall health. Understanding UV levels helps you prevent sunburn and reduces the long-term risks of skin damage and diseases. Given our Cwb climate, which features both warm temperatures and high altitudes, the potential for intense UV exposure is significant—especially during peak hours from 10:00 AM to 3:00 PM when the UV Index can soar to as high as 15. Awareness of these conditions empowers residents and visitors alike to make informed decisions about outdoor activities, ensuring safer sun exposure and healthier skin.
As the sun rises, the UV Index starts off gently at 1 between 07:00 and 08:00, perfect for early morning strolls. However, by 09:00, it climbs to 2, indicating a slight increase in UV radiation. The real surge occurs around 10:00, when the index jumps to 5, signaling that it’s time to be cautious. From 11:00, the UV levels escalate dramatically, hitting 9 at noon and peaking at a scorching 15 by 14:00. This period, particularly from 12:00 to 14:00, represents the highest risk for sun exposure with the index soaring to 14. As the afternoon progresses, the UV Index begins to wane, dropping to 9 by 16:00 before tapering off to 2 by 18:00 and settling back to 1 by 19:00. Make sure to protect your skin during peak hours! 🌞
