Understanding the UV Index in Jayapura, Indonesia is crucial for safeguarding our skin and overall health. With the tropical climate of Jayapura, where UV levels can soar, awareness of the UV Index helps in preventing sunburn and reducing the risk of long-term skin damage. During peak hours, particularly between 10:00 AM and 1:00 PM when the index can hit a staggering 11, it's vital to take protective measures. Knowing the daily UV levels empowers residents and visitors alike to enjoy the beautiful outdoors while prioritizing their skin health.
As the sun rises and begins to assert its strength, the UV Index increases rapidly throughout the morning. At 7:00 AM, it starts at a modest 2, but by 9:00 AM, it leaps to a notable 7. The peak intensity hits high noon, with 11 at both 11:00 AM and 12:00 PM, indicating a critical time for sun safety. After that, the index begins to drop, falling to 6 by 2:00 PM and further declining toward the evening, finally reaching 0 by 7:00 PM. This data starkly illustrates the importance of sun protection during the midday hours when UV exposure is at its most dangerous.
