As the seasons change, so does exposure to ultraviolet (UV) radiation, significantly impacting both residents and visitors. January and December have a moderate UV Index of 4, allowing for a safer burn time of 30 minutes before risk increases. However, as we move into February, the UV Index rises to 7 (high), and by March, it escalates to 10 (very high), with burn time plummeting to just 15 minutes. The peak months for UV exposure are April to August, where the Index reaches 13-14 (extreme), demanding vigilant sun protection measures with burn times reduced to only 10 minutes. September marks a gradual decrease, but a high Index of 11 still necessitates caution. As the year closes with October and November presenting high levels again (7 and 6), it is essential for individuals to remain aware of changing UV levels and take appropriate precautions regardless of the season, notably during these high-risk months. Always consider wearing sunblock, protective clothing, and seeking shade during peak UV hours, particularly between 10 AM and 4 PM.
