The UV Index shows a significant seasonal variation, with the highest values occurring during the summer months of May through August, where it reaches an extreme level of 16 to 18. March and April also present very high to extreme UV levels, indicating a notable increase in risks for skin damage. The high-risk months for UV exposure are therefore primarily from March to September, with April and May being the most critical. To protect yourself from harmful UV rays during these months, it's essential to apply broad-spectrum sunscreen, wear protective clothing, and seek shade during peak sunlight hours. Conversely, during January, December, and November, the UV Index drops to moderate and high levels, allowing for more manageable exposure. Visitors and residents should remain vigilant, adjusting their sun safety practices as the months progress, especially when the UV Index peaks.
