The highest risk months are April to August, with values consistently at 8 or above, suggesting severe caution for sun exposure. Visitors and residents are advised to limit outdoor activities during peak hours (10 AM - 4 PM) and to wear protective clothing, apply broad-spectrum sunscreen, and seek shade whenever possible, particularly in the very high and extreme categories.
