Understanding the UV Index in Porto Covo, Portugal is crucial for safeguarding your skin and enjoying the sun responsibly. As this picturesque coastal town experiences a Mediterranean climate (Csa), residents and visitors alike should be aware of the varying UV levels throughout the day. With peak UV Index readings reaching 10 around midday, awareness is key to preventing sunburn and long-term skin damage. By staying informed about daily UV exposure risks, you can protect yourself and make the most of Porto Covo's stunning beaches and sunny afternoons.
The UV Index chart reveals a dynamic daily pattern of solar intensity. Starting early in the day, the UV Index remains low, peaking at 1 by 08:00. However, as the sun reaches its zenith, the index surges dramatically—hitting 7 by 11:00 and soaring to a maximum of 10 between 13:00 and 14:00. This signals a critical window for sun exposure, where protection is essential. As the afternoon progresses, the UV levels begin to decline, dropping to 4 by 17:00, before tapering off to 1 again by evening. To stay safe, it's vital to be cautious during those peak hours!
