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.
