Understanding the UV Index is crucial for residents and visitors in Liji, China, where the sun's intensity can pose significant risks to skin health. With UV levels peaking at 10 during midday, awareness of these fluctuations can aid in preventing sunburn and long-term skin damage. Liji's Cwa climate—characterized by a distinct wet and dry season—means that UV exposure can vary greatly throughout the year. By staying informed about the UV Index, you can take appropriate precautions and enjoy the beautiful outdoors while keeping your skin safe.
The UV Index data reveals an interesting pattern throughout the day, peaking during the midday hours. Starting at 07:00, the index begins at a modest 2, gradually climbing to an impressive 10 by 11:00 and holding steady until 13:00. This high UV exposure hour signals the need for sunscreen or protective clothing. As the afternoon progresses, the index gently descends, tapering down to 8 by 14:00, and then down to 6 at 15:00. The sun's intensity continues to wane, with the index falling to 3 at 16:00 and further dropping to 1 by 18:00 and 19:00. Planning outdoor activities? Aim for the morning or early afternoon when the sun is at its brightest but remember to stay protected during those peak hours!

As the seasons change, so do the patterns of UV exposure, with significant increases typically observed from March through September. The high-risk months for UV exposure are April through September, when the UV Index often reaches very high to extreme levels, particularly peaking in June at an Index of 11. Residents and visitors should be particularly cautious during these months, as the potential for skin damage increases dramatically; burn times can drop to as little as 10 minutes in June. To protect yourself, it's recommended to apply sunscreen regularly, wear protective clothing, and seek shade during peak sun hours. From October to February, the UV levels decrease significantly, with burn times extending back to 30 minutes in January and November, making outdoor activities safer, but still requiring some level of UV protection during sunny days.
