In Suzaka, Japan, understanding the UV Index is crucial for protecting your skin and overall health from the sun's harmful rays. As a resident or visitor in this region, being aware of the UV levels can help you prevent sunburn and reduce the risk of long-term skin damage. With a Dfb climate, Suzaka experiences a mix of sunny days and cloud cover, but when UV levels peak—reaching a high of 11 between noon and 1 PM—it's vital to take proper precautions. Whether you're enjoying a day outdoors or participating in local activities, staying informed about the UV Index empowers you to make safe choices for sun exposure.
The UV Index showcases an intense midday sun, peaking at 11 between 11:00 AM and 12:00 PM. As the day progresses, the UV levels rise quickly; from a mild 2 at 07:00 AM, they soar to 9 by 10:00 AM, reflecting an increasing urgency for sun protection. The midday hours are particularly critical, where skin can suffer damage after just 15 minutes of exposure. After 2:00 PM, there’s a gradual decline in UV intensity, dropping to 5 by 3:00 PM, then to a safer 2 by 5:00 PM, finally decreasing to 0 after 6:00 PM. This data emphasizes the importance of staying mindful of UV exposure, especially during the peak hours.
