In Kamogatacho-kamogata, Japan, understanding the UV Index is crucial for protecting your skin from harmful sun exposure. With the potential for high UV levels, especially during midday hours, being aware of these values can help prevent sunburns and promote long-term skin health. The region experiences a humid subtropical climate (Cfa), leading to increased UV risks, particularly in the warmer months. As you plan your outdoor activities, keeping an eye on the UV Index will ensure you take the necessary precautions to enjoy the sun safely.
As the day unfolds, the UV Index climbs steadily, peaking at a striking 12 around noon, signaling a high risk for skin damage without protection. Early risers at 07:00 encounter a mild 2, but the intensity increases quickly, reaching 9 by 10:00 and a critical 11 by 11:00. From 12:00 to 13:00, the index holds its highest point at 12, making it essential to seek shade or apply sunscreen. After 13:00, the UV levels gradually decrease, dropping back to a manageable 4 by 16:00 and winding down to a safe 1 by 18:00. This hourly data serves as a reminder to take sun safety precautions, especially during peak hours.
