Understanding the UV Index in Saint-Theophile, Canada is crucial for protecting yourself and your loved ones from the harmful effects of ultraviolet radiation. With a Dfb climate that brings warm summers and snowy winters, residents should be aware of the UV levels that can lead to sunburn and long-term skin health issues. During peak hours, especially between 11 AM and 1 PM, the UV Index can reach as high as 10, indicating a very high risk of harm from unprotected sun exposure. By staying informed about daily UV levels, you can take proactive steps to safeguard your skin while enjoying the beautiful outdoors in Saint-Theophile.
As the sun rises, the UV Index gently climbs from a mild 1 at 07:00 to a moderate 3 by 08:00. By 09:00, it reaches a passable level of 4, but the real intensity begins to peak as the hour strikes 10:00, reaching 6. The UV Index hits its zenith at 12:00 and 13:00, rocketing to a striking 10, urging everyone to seek shade and wear sun protection. As the afternoon wanes, it gracefully descends: dropping to 9 at 14:00, then tapering off to 7 by 15:00, and gently falling to 5 at 16:00. Evening brings relief, as the index stabilizes at 3 by 17:00, and finally retreats to a comfortable 1 at 19:00.
