Throughout the year, the UV Index experiences significant seasonal changes, influencing the risk of sunburn for residents and visitors alike. During the winter months of January and December, the UV levels are relatively low (UV Index 2), requiring minimal sun protection, with a burn time of up to 45 minutes. However, as spring and summer approach, the UV Index escalates sharply, peaking in July and August at an extreme level of 11, where the burn time is drastically reduced to just 10 minutes. This indicates that March through September are the high-risk months for sun exposure, particularly with very high to extreme levels from April through August. It is crucial for everyone to take precautions during these months by wearing sunscreen, protective clothing, and seeking shade to minimize UV damage. As the UV Index begins to decrease in the fall, it is still advisable to maintain sun safety practices until the levels return to low in December.
