As the seasons change, so does the UV Index, significantly impacting sun safety for visitors and residents. From January to February, the UV Index remains at a moderate level (3 to 4), allowing for a burn time of up to 30 minutes. However, as spring approaches in March with an increase to a high UV Index of 6 and a burn time of 25 minutes, caution becomes essential. April and May see a steep rise to a very high exposure (UV Index 8-10), reducing the safe burn time to just 15 minutes. The peak of UV intensity occurs in June with an extreme UV Index of 11, demanding vigilant sun protection as burn time is just 10 minutes. July and August maintain the very high levels (10), while September and October witness a gradual decline, with the UV Index falling to 8 and 7, respectively, allowing for longer exposure times of 15 and 25 minutes. As November and December arrive, the UV Index drops back to a moderate level, corresponding to a return to 30-minute burn time. Given these fluctuations, it is crucial for everyone to take appropriate precautions during March to October, particularly in the peak summer months, utilizing sunscreen, protective clothing, and seeking shade when necessary.
