Understanding the UV Index in Borborema, Brazil is essential for safeguarding your skin and overall health. With high levels of ultraviolet radiation, especially between 10:00 AM and 2:00 PM, it’s crucial to stay informed about UV exposure risks to prevent sunburn and long-term skin damage. The tropical climate here means more sun and higher UV levels, particularly in the summer months. Protect yourself by checking the UV Index regularly and taking precautions when the sun's rays are strongest—because a little awareness can go a long way in preserving your skin health!
As the day breaks, the UV Index gradually rises, peaking at a robust 8 at 12:00 PM, signaling the sun's intensity is at its highest. Starting from a mild 1 at 07:00 AM and 08:00 AM, the UV levels steadily climb, hitting 5 by 10:00 AM. By 11:00 AM, a brisk 7 indicates that sun safety measures are essential. The intensity slightly declines after noon, tapering off to 6 at 2:00 PM, and then gradually decreases to a 4 by 3:00 PM. By evening, the UV Index drops back to a mere 1 at 5:00 PM and ultimately falls to 0 after 6:00 PM, signaling a safe return home as the sun sets. Keep this UV pattern in mind for outdoor activities to protect your skin and enjoy the day!
