Seasonal UV changes reveal a marked increase in UV Index values from January through August, peaking at 14 in both April and August, which falls into the extreme exposure category. The high-risk months for UV exposure are typically from February to September, where the UV Index remains at or above 11, requiring sensitivity to skin safety.

Visitors and residents are strongly advised to take precautions by wearing sunscreen, protective clothing, and seeking shade during peak sun hours to minimize health risks associated with high UV exposure. As autumn and winter approach, UV levels decrease, but the very high exposure category in January, November, and December still necessitates attention, with burn times extending to 15 minutes. Staying informed and protecting against UV radiation is crucial year-round.
