The high-risk months are from April to August, where the UV Index peaks at 9 in July, indicating very high exposure risk with a burn time as low as 15 minutes. Visitors and residents are advised to take extra precautions during these months, including wearing protective clothing, applying broad-spectrum sunscreen, and seeking shade during peak sun hours.
