In Oregon, understanding the UV Index is essential for protecting your skin and overall health. By staying informed about UV levels, you can effectively prevent sunburn and minimize long-term skin damage. Oregon's climate, characterized by its distinct seasons and often unpredictable weather, brings varying UV exposure risks throughout the year. During peak hours, especially from 11 AM to 1 PM, UV levels can reach dangerously high values, emphasizing the need for vigilance even on cloudy days. Don’t let the beauty of the Oregon outdoors lead to unintended harm—stay UV aware!
The UV Index dramatically peaks during the midday hours, showcasing a clear pattern of solar intensity. Starting from a mild 1 at 07:00, it steadily rises, reaching a notable 11 by 13:00.

With the sun's intensity waning, the cooler evening hours promise a gentle close to the day, offering a more comfortable outdoor experience. Always stay vigilant during peak UV times!
