In Ambatofinandrahana, Madagascar, understanding the UV Index is crucial for safeguarding your skin from harmful ultraviolet rays. With UV levels peaking at 8 during midday hours, awareness can help prevent sunburn and maintain long-term skin health. The region's Cwb climate offers a mix of pleasant temperatures but also raises exposure risks when UV levels are high, particularly between 10 AM and 2 PM. Stay informed about UV fluctuations throughout the day to enjoy the sun safely while protecting your skin!
As the sun climbs higher in the sky, the UV Index makes a notable ascent. At 7:00 AM, it starts at a low 1, signaling a gentle introduction to the day. By 9:00 AM, the index doubles to 4, marking the onset of a mild sun exposure, but it's not until 12:00 PM that the intensity peaks at a robust 8—a strong reminder to seek shade and apply sunscreen. The afternoon sees a gradual decline, with values dropping to 5 at 2:00 PM and diminishing to a soft 0 by 6:00 PM. This data highlights the importance of protecting your skin during those prime sun hours, particularly between 11:00 AM and 1:00 PM, when exposure is at its highest.

The autumn months bring another spike in risk, particularly in September, with the index returning to an extreme level of 12.
