In the picturesque town of Angustias, Portugal, understanding the UV Index is crucial for safeguarding your skin and overall health. With the sun reaching peak UV levels, particularly between 11:00 AM and 3:00 PM, awareness of these levels can be the difference between enjoying the outdoors and suffering from painful sunburns or long-term skin damage. Angustias boasts a Cfb climate, characterized by mild summers and moderate exposure, yet it's essential to recognize that even on seemingly benign days, UV rays can pose significant risks. By staying informed and taking proper precautions, you can fully enjoy the beauty of Angustias while protecting your skin from the sun's powerful effects.
The UV Index data reveals a dynamic sun exposure pattern throughout the day. Starting with a low index of 1 in the early hours (07:00 and 08:00), sun sensitivity increases as the day progresses. By 09:00, the index rises to 2, marking the beginning of heightened UV intensity. The peak occurs between 12:00 and 14:00, where it hits a high of 10, indicating a strong need for sun protection. As the afternoon wanes, the levels gradually decline, sliding to 8 at 16:00 and further down to 3 by 18:00. By 19:00, the exposure reduces to 2, suggesting a safe transition as daylight fades. Remember, when the UV Index is 6 or higher, it’s essential to take protective measures!

As the seasons change, so do the UV index levels, with highest risks typically occurring from April to September. During these months, especially in June when the UV index reaches an extreme level of 11, the burn time is as short as 10 minutes. Visitors and residents should be particularly vigilant during this period, taking necessary precautions such as applying sunscreen with a high SPF, wearing protective clothing, and limiting sun exposure during peak hours. Conversely, during the winter months from January to March, the UV levels are substantially lower, categorized as moderate to high, allowing for safer outdoor activities with burn times ranging from 25 to 30 minutes. It’s crucial to remain aware of these seasonal changes to protect skin health throughout the year.
