In Yuzhno-Sakhalinsk, staying informed about the UV Index is crucial for the health and well-being of its residents. Understanding UV levels can help prevent harmful sunburn and protect skin health, particularly in a region characterized by its Dfc climate, which combines cool summers with significant sun exposure during peak hours. With midday UV Index levels reaching 9, it’s essential to take precautions to minimize risks while enjoying outdoor activities.

As the sun rises, the UV Index gradually climbs, starting at a low of 1 by 07:00 and 08:00. The real leap begins at 09:00, where it reaches 3, escalating to 4 by 10:00. As noon approaches, the UV Index peaks at an impressive 9 from 13:00 to 14:00, making it crucial to take protective measures during those hours. Afterward, it begins to taper off, dropping to 6 by 16:00, and further declining through the late afternoon and evening, eventually falling back to 1 by 19:00. For those venturing outdoors, staying vigilant to the UV levels during the midday hours is essential for skin protection!

Throughout the year, the UV Index experiences significant seasonal changes, with the highest values occurring in the summer months. From January (UV Index 2) to March (UV Index 4), exposure levels are relatively low to moderate, allowing for longer burn times of 30–45 minutes. However, as we transition into April (UV Index 6) and May (UV Index 7), the risk escalates into the high category, reducing burn times to 25 minutes. The peak risk months are June and July, when the UV Index reaches 8–9, categorized as very high, with a burn time of just 15 minutes. August sees a slight decline (UV Index 8), but remains critical. In September (UV Index 7) and October (UV Index 4), the risk decreases again, returning to moderate levels with burn times of 25–30 minutes. November and December return to low risk with extended burn times of 45 minutes. Visitors and residents are advised to take precautions during the high-risk months, particularly from April to September, by wearing protective clothing, applying sunscreen regularly, and seeking shade during peak sunlight hours.
