As the seasons change, so too does the UV Index, significantly influencing the risk of sun exposure. From January to February, the UV levels rise moderately, with February marking the transition to a moderate exposure category (UV Index 3), leading to a burn time of 30 minutes. The risk escalates sharply in April, reaching a very high UV Index of 9, peaking at 10 from May through August, where visitors and residents are at considerable risk with a mere 15 minutes until burn time. September sees a slight decline to an 8 while maintaining a very high exposure level. As autumn approaches, the UV Index drops back to 5 in October and returns to low levels by December. Therefore, it is crucial for everyone, particularly during the high-risk months of April to September, to take protective measures such as applying sunscreen, wearing protective clothing, and seeking shade during peak sunlight hours to minimize the risk of skin damage.
