Understanding the UV Index is crucial for residents and visitors in Samlout, Cambodia, where the tropical climate can lead to high levels of sun exposure.

Given the region's climate, it's essential to stay informed about daily UV risks to protect yourself and enjoy the beautiful outdoors safely. Whether you’re planning a day at the market or exploring the stunning landscapes, knowledge of the UV Index can help you stay safe under the sun.

The UV Index experiences notable seasonal variations, remaining at an extreme level throughout most of the year. From January to September, the UV Index consistently ranges from 11 to 15, with March, April, and September being particularly high at 15. The months of February and March are particularly critical, reaching a peak of 13 and 15, respectively, indicating a higher risk for harmful UV exposure.
