Throughout the year, UV Index levels show significant seasonal variation, with high-risk months typically occurring from May to August. In June, the UV Index peaks at 8, indicating a very high risk of harm from unprotected sun exposure, with a burn time reduced to just 15 minutes. Conversely, from January to February and again in November to December, the UV Index remains low (1-2), allowing for longer exposure times (up to 45 minutes) without significant risk. As such, for residents and visitors, it is strongly advised to take protective measures during the high UV months, particularly from May to July, which includes wearing sunscreen, protective clothing, and limiting sun exposure during peak hours. During the winter months, while the risk is lower, it's still wise to remain cautious as UV rays can still cause skin damage.
