In Kurume, Japan, an understanding of the UV Index is crucial for protecting your skin and overall health. With typical Cfa climate conditions, Kurume experiences significant UV exposure, especially during the midday hours when the index can soar to as high as 12. Awareness of UV levels can help residents and visitors alike take necessary precautions against sunburn and long-term skin damage. As the sun climbs to its peak, usually around noon, the risk for harmful ultraviolet radiation increases dramatically, highlighting the importance of checking the UV Index regularly to enjoy the outdoors safely.
During the morning hours, the UV Index starts off low at 1 at 7:00 AM, indicating minimal risk of harm from unprotected sun exposure. As the day progresses, the intensity ramps up, peaking at 12 around 12:00 PM and 1:00 PM, suggesting a high risk for harm, especially for those spending extended periods outdoors. Post-peak, the index gradually declines, dropping to 7 at 3:00 PM and further down to 1 by 7:00 PM, which indicates a return to minimal risk as the sun sets. For sun enthusiasts, midday offers the most intense UV radiation, making sun protection essential during those hours!
