In Bella Union, Uruguay, being aware of the UV Index is crucial for protecting your skin and overall health. Understanding the UV levels throughout the day is essential for sunburn prevention and maintaining skin health, especially in a region characterized by its Cfa climate, which often brings high levels of sun exposure. With peak UV readings reaching 5 around midday, locals and visitors alike should stay informed about daily UV fluctuations to minimize risks of harmful effects while enjoying the great outdoors. Embrace the sun wisely and keep your skin safe!
The UV Index data for the day paints a clear picture of sun intensity as the hours progress. Starting at 07:00, the index is at a comfortable 0, allowing for a worry-free morning. As we move into the 08:00 and 09:00 hours, it remains low at 1, perfect for outdoor activities. This gradual increase peaks at 12:00 and 13:00, reaching a maximum of 5, indicating that sun protection is a must during these hours. The intensity then gradually tapers off, bringing it back down to 4 at 14:00 and declining further to 0 by 19:00. Embrace the early hours, but don’t forget your sunscreen when the sun is at its zenith!

September returns to very high exposure (UV Index 9), while in October and November, the UV index returns to extreme levels (UV Index 12 and 14), with a consistent 10-minute burn time.
