As the seasons change, so do the UV Index levels, significantly affecting outdoor activities. The winter months of January and December present a low risk with an index of 2, allowing for safe sun exposure of up to 45 minutes. However, as we transition into spring, particularly March and April, the risk escalates to high levels (UV Index 6 and 7), with burn times decreasing to 25 minutes. The summer months of May through August pose the highest risk, characterized by very high UV Index levels of 9 to 10, where even short exposures of 15 minutes can result in burns. September marks a slight decline to high exposure (UV Index 7) and then reduces again in October and November to moderate levels (UV Index 5 and 3). Residents and visitors are strongly advised to take precautions during the high-risk months from March to August, including wearing protective clothing, applying sunscreen regularly, and seeking shade during peak hours to minimize UV exposure.
