Understanding the UV Index in Punta Alta, Argentina is essential for protecting your skin and overall health. With the region's Cfa climate bringing conditions that can lead to high UV exposure, it’s crucial to stay informed about the daily UV levels. Higher UV Index readings—especially around midday, peaking at 4—indicate an increased risk of sunburn, making it vital to take precautionary measures when outdoors. By being aware of these levels, you can enjoy the beautiful sunny days in Punta Alta while keeping your skin safe and healthy.
The UV Index skyrockets as the sun climbs higher, peaking at 12:00 PM with a level of 4, indicating a moderate risk of harm from unprotected sun exposure. As the daylight progresses, 07:00 starts at a cool 0, gradually rising to 1 by 08:00 and 09:00. By 10:00, it hits 2, and by 11:00, it reaches 3, setting the stage for that midday high. Later in the afternoon, from 12:00 to 14:00, the index maintains its strength at 4, before gently tapering off as the sun begins to set. By 19:00, it’s back to 0, marking the end of a sun-filled day. Stay protected during those peak hours!
