Throughout the year, the UV Index exhibits notable seasonal fluctuations, with significant increases during the late spring and summer months. From January to February, the UV Index remains low (1-2), allowing for safe exposure times of up to 45 minutes. However, as we transition into March, the index rises to a moderate level (3), reducing safe exposure to 30 minutes. The peak risk months are April through August, where the index reaches high levels (6-7), resulting in burn times of only 25 minutes; this is when it is crucial for visitors and residents to take protective measures. The UV Index then begins to decrease in September (5) and further in October to December (1-2), allowing for longer exposure times again.
