In San Miguel de Tucumán, understanding the UV Index is essential for protecting your skin and maintaining overall health. With summer temperatures soaring and plenty of sunshine, knowing the UV levels can help you avoid painful sunburns and long-term skin damage. The city's Cwa climate leads to notable daily UV exposure, particularly between 11:00 AM and 2:00 PM, when the index peaks at 5. By staying informed about the UV Index, you can enjoy your outdoor activities safely while safeguarding your skin from harmful rays.
The UV Index throughout the day offers a telling glimpse into solar intensity. Starting low at 07:00 with a UV Index of 0, it gradually rises, reaching 1 by 08:00 and 09:00. By 10:00, it inches up to 2, more noticeable as the day progresses. The peak sunlight unfolds around 12:00 to 14:00, where the index skyrockets to a maximum of 5. As the afternoon wanes, protective measures become less urgent, with the index decreasing to 4 at 15:00 and dropping to 2 by 16:00. By the evening, UV exposure diminishes significantly, descending back to 1 at 17:00 and returning to 0 by 19:00. It’s a classic reminder to stay sun-safe during those midday hours!

Moving into the summer, from May to August, the risk reduces somewhat with indices of 7 to 6, categorized as high to moderate, allowing for slightly longer safe exposure times. Visitors and residents should take priority in protecting their skin, particularly during high-risk months—applying sunscreen, wearing protective clothing, and seeking shade—especially in those extreme months for their safety.
