Understanding the UV Index in Yanshan, China, is crucial for safeguarding your skin against the harmful effects of UV radiation. As you enjoy the city’s vibrant outdoors, it’s essential to be aware of varying UV levels throughout the day, especially during peak hours, to prevent sunburn and maintain long-term skin health. Given Yanshan’s Cfa climate characterized by hot summers and high sun exposure, the potential risks for increased UV levels—peaking at a staggering 12 around midday—make it vital to stay informed and protected. Prioritizing UV awareness helps ensure your adventures are both enjoyable and safe.
As the sun rises, the UV Index begins its ascent, starting at a mild 1 at 07:00 and gently climbing to 2 by 08:00. The warmth of midday brings a significant surge, with the index peaking at a striking 12 between 12:00 and 13:00—a reminder to stay protected with sunscreen and hats! As the afternoon progresses, the levels gradually decline, dropping to 8 by 15:00 and further easing back to 1 by the time the sun sets at 19:00. This hourly fluctuation highlights the importance of being mindful of UV exposure, especially during those peak hours when the sun’s rays are strongest!

Throughout the year, UV Index levels show significant seasonal changes, with higher values typically from late winter through early autumn. The high-risk months for UV exposure are February to September, where indices reach extremes of 11 to 13. Particularly, March to August marks the peak of intense exposure, warranting caution, as the burn time drops to just 10 minutes for these months. Visitors and residents are strongly advised to take protective measures during these periods by wearing sunscreen, sunglasses, and protective clothing, and to seek shade whenever possible, especially between 10 AM and 4 PM when UV radiation is at its highest. In January, October, and November, while the UV Index decreases, it's still prudent to take care as levels remain high to very high during those months.
