Understanding the UV Index is crucial for residents and visitors in Syumsi, Russian Federation, where the climate promotes both outdoor activity and potential sun exposure risks. With UV levels varying throughout the day—peaking at a UV Index of 6 during midday—it’s essential to recognize these fluctuations in order to prevent sunburn and maintain optimal skin health. By staying informed about local UV conditions, you can take proactive steps to protect yourself, particularly in this Dfb climate, which can lead to increased UV exposure during sunny days. Whether you're enjoying a leisurely stroll or engaging in outdoor sports, awareness of UV levels can significantly enhance your sun safety strategy.
As the sun rises, the UV Index gradually climbs, reaching its peak at 12:00 PM with an impressive 6. From the early hours of 7:00 AM, when it starts at a mild 1, it steadily increases, hitting 2 by 8:00 AM and escalating to 4 at 10:00 AM. By 11:00 AM, caution is warranted with a rating of 5. The afternoon sun maintains its intensity, keeping the index at 6 between 12:00 PM and 1:00 PM. However, as the day winds down, the UV Index begins to recede—falling back to 5 by 2:00 PM, then 4 at 3:00 PM, and finally settling at 1 by 7:00 PM, signaling a safer time for outdoor activities. Always remember to protect your skin during the peak hours!
