Understanding the UV Index is crucial for residents and visitors of Tomsk, Russian Federation, where the unique climate can expose individuals to varying levels of ultraviolet radiation. Being aware of UV levels not only helps in effectively preventing sunburn but is vital for maintaining long-term skin health. Given Tomsk's Dfc climate, characterized by cooler temperatures but occasionally intense sunlight, it's essential to monitor UV exposure, especially during peak hours when levels can reach up to 6. Staying informed allows you to enjoy the outdoors while protecting your skin from harmful effects!
Starting off the day, the UV Index is quite low at 07:00, peaking at 1. As the morning unfolds, it gradually rises, reaching 2 by 08:00 and climbing to 3 at 09:00. By 10:00, the intensity escalates to 4, hitting moderate levels. The sun reaches its zenith between 11:00 and 13:00, with the UV Index peaking at 6. This elevated risk remains consistent until 15:00, where it holds steady at 6. As the afternoon wanes, the intensity declines; by 16:00, it drops to 4, further decreasing to 3 at 17:00, and finally tapering off to 2 and 1 as the evening sets in at 18:00 and 19:00. Stay protected during those peak hours when the UV Index is at its highest!

Throughout the year, the UV Index exhibits significant seasonal changes that necessitate attention from both visitors and residents. From January to February, the UV Index remains low (1-2), allowing for a safer outdoor experience with a burn time of 45 minutes. As spring approaches, March and April see a rise to a moderate level (4-5), with burn times decreasing to 30 minutes, marking the beginning of higher UV exposure. The summer months of May to August present the highest risk, with a UV Index peaking at 7 and a burn time of only 25 minutes. This marks a critical period for sun protection, particularly in June and July, which are considered high-risk months. As autumn sets in, the UV Index gradually declines to moderate levels in September and October, offering a slight reprieve with burn times returning to 30 minutes. Finally, from November to December, the exposure risk diminishes once again to low levels, reminiscent of the early year. It is essential for everyone to take precautions during the high-index months—using sunscreen, wearing protective clothing, and seeking shade to minimize skin damage and enhance safety during outdoor activities.
