As the seasons change, so does the UV Index, reflecting fluctuations in UV radiation exposure throughout the year. The highest risk months generally occur from April to August, where the UV Index reaches peak levels of 8 to 10, indicating very high exposure and a burn time as short as 15 minutes. Visitors and residents are strongly advised to take protective measures during these months, such as wearing sunscreen, sunglasses, and protective clothing. In contrast, January and December are safer months with a low UV Index of 2, allowing for longer exposure times of 45 minutes. However, even during moderate months like February, October, and November, UV precautions remain important, as burn times drop to 30 minutes. Staying informed and protecting your skin year-round is essential for health and safety.
