Winter months (January and December) present low UV Index levels of 2, allowing for relatively safe outdoor activities with a longer burn time of 45 minutes. As spring approaches, February and March see an increase to a moderate UV Index of 4 and 5, with a burn time of 30 minutes. April marks the transition to higher risk, with an index of 6 (high exposure) and burn time reducing to 25 minutes. The summer months (May to August) are particularly critical, characterized by very high UV Index levels of 8 to 9, where exposure should be limited to just 15 minutes to prevent burns.
