Throughout the year, seasonal UV changes reveal fluctuating levels of sun exposure, with the months of May through August marked by extreme UV Index values of 10 or higher, posing the highest risk for sunburn and skin damage. March and April also see a rise to very high levels (8-10), indicating a significant increase in UV radiation as spring progresses. The high-risk months are therefore clearly identified as May to August, where a UV Index of 12 remains consistent, equating to a burn time of just 10 minutes. Residents and visitors are advised to take precautions during these months, including wearing sunscreen with high SPF, protective clothing, and seeking shade whenever possible, particularly during midday hours when the sun's rays are strongest. During the lower UV months—from November to February—while the exposure is moderate, it’s still recommended to practice sun safety, especially on bright, clear days.
