Understanding the UV Index is crucial for residents and visitors in San Jorge, Guatemala, where the sun's intensity can pose significant health risks. With peak UV levels soaring as high as 14 during the midday hours, being informed about UV exposure is key to preventing sunburn and protecting your skin health. The region's climate, characterized as Am, brings warm temperatures and ample sunshine, increasing the likelihood of skin damage if proper precautions are not taken. Stay informed and enjoy the outdoors safely by keeping an eye on the UV Index!
The UV Index tells a compelling story throughout the day, starting off with a gentle 1 at 7:00 AM. As the sun ascends, it charges up rapidly, reaching a moderate 4 by 8:00 AM. The intensity peaks at 12:00 PM with an intense 14, suggesting that this is the time to seek shade and take precautions against sunburn. The index gradually declines thereafter, dropping to 6 by 3:00 PM, and further down to a safe 1 at 5:00 PM. As evening sets in, the UV rays diminish, leaving a 0 at 7:00 PM. It's clear: the midday hours are when the sun is most powerful, so plan accordingly to protect your skin!
