In Puerto Yerua, Argentina, awareness of the UV Index is essential for maintaining skin health and preventing sunburn. Understanding the UV levels throughout the day helps residents and visitors take appropriate precautions against harmful ultraviolet radiation. Given Puerto Yerua's Cfa climate, characterized by a warm temperate environment, the sun can pose significant exposure risks, particularly from mid-morning to early afternoon when UV levels peak at 5. Being informed and proactive about the UV Index can safeguard your skin while you enjoy the beautiful Argentine sunshine.
The UV Index throughout the day presents a clear pattern of rising and falling intensity. Starting from a maximum of 0 at 7:00 AM, the index gradually increases, reaching 1 by 8:00 AM and maintaining that level until 10:00 AM. As the sun climbs higher, the intensity spikes to 4 at 11:00 AM, peaking at 5 during the midday hours of 12:00 PM to 2:00 PM. This period signifies the most potent sun exposure, calling for protective measures. Afterward, the index begins to decline, dipping back to 3 by 3:00 PM, and settling at 1 by 5:00 PM. By 7:00 PM, it returns to 0, signaling a gentle end to the day's UV intensity. Remember to stay sun-safe during those peak hours!

Throughout the year, UV Index levels exhibit significant seasonal variations, with the highest risk occurring during the winter months. From January to March, the UV Index remains extremely high, reaching a peak of 15 in January, where a mere 10 minutes of exposure can result in skin burns. This extreme risk continues into October and November, maintaining an index of 13 and 14 respectively, again allowing for only 10 minutes of safe exposure. As the seasons shift into spring and summer, the UV levels decrease, with April seeing a very high index of 8, and then moderating further to levels of 5 to 6 from May to August. September marks a return to very high levels at 9 before the winter extremes resume. Given this data, it is crucial for both visitors and residents to exercise caution, particularly during the high-risk months of January, February, March, October, and November. It is advisable to use sunscreen, wear protective clothing, and limit direct exposure during peak UV hours to minimize skin damage and health risks.
