Throughout the year, seasonal UV changes significantly impact sun exposure and potential skin damage. During the early months of January and December, the UV Index is moderate (5 and 4 respectively), allowing for longer burn times of 30 minutes. However, as spring approaches, there's a notable increase, reaching very high levels by March (8) and April (10).
