Understanding the UV Index is crucial for residents and visitors of Freamunde, Portugal, especially during the warmest months when the sun's rays can lead to harmful effects. Not only does being aware of UV levels help you prevent sunburn, but it also plays a vital role in maintaining your skin health in the long run. With Freamunde's Csb climate, characterized by mild, wet winters and warm, dry summers, the local UV exposure can spike during mid-day hours, reaching a peak UV Index of 11 around noon. By keeping an eye on the UV forecast, you can enjoy the sunny weather while protecting yourself from its potential hazards.
The UV Index for the day reveals a dynamic shift in sun exposure, starting off low in the early morning hours with values of 1 at both 7:00 and 8:00. As the sun climbs higher, the index ramps up, peaking at an intense 11 between 13:00 and 14:00—a clear signal for sun safety measures. This period of maximum intensity comes after a sharp rise from 3 at 9:00 to a notable 7 at 11:00. The afternoon provides a gradual decline, with levels falling to 9 by 15:00, then tapering off to 3 by 18:00 before returning to a safe 1 at 19:00. It's a solid reminder to stay protected during peak hours!

As the seasons change, so do the UV levels, which significantly impact skin safety for both visitors and residents. The UV Index starts low in January (2) and December (2), indicating a low risk for sunburn. However, as we move into the spring and summer months, particularly from March (6) to August (9), the risk escalates, with April (8) and the peak in June (11) classified as extreme. The high-risk months are primarily from April through August, where burn times are notably short, especially in June, with only 10 minutes until skin damage occurs. It is crucial for individuals during these months to take necessary precautions, such as wearing sunscreen, protective clothing, and limiting sun exposure, especially during peak hours. As fall approaches, the UV Index gradually decreases, but awareness remains essential for safe outdoor activities.
