As the seasons change, so does the UV Index, highlighting the importance of sun safety for both visitors and residents. From January to February, the UV levels remain in the moderate range (3-4), allowing for relatively safe outdoor exposure with a burn time of 30 minutes. However, by March, the UV Index escalates to high (6) with a reduced burn time of 25 minutes, signaling a shift. The peak risk occurs from April to August, with UV Index levels reaching very high (9-10) and extreme (11) ratings, particularly in July and August, where the burn time drastically reduces to just 10 minutes. As autumn approaches, UV exposure decreases, dropping to high in October and moderate levels again in November and December. It is crucial for everyone to take appropriate precautions, especially during the high-risk months of April to August, by wearing protective clothing, applying sunscreen frequently, and seeking shade during peak hours to minimize sunburn risks.
