Throughout the year, seasonal UV changes demonstrate significant fluctuations in intensity, with the highest UV Index values occurring from May to September. During these months, particularly in July and August, the UV Index peaks at 14, categorizing exposure as extreme and resulting in a dangerously short burn time of just 10 minutes. High-risk months, notably March through October, require heightened awareness and protective measures, as even moderate exposure can lead to skin damage. Residents and visitors should be advised to take precautions, such as wearing sunscreen, protective clothing, and sunglasses, especially during midday hours when UV radiation is strongest. As the year transitions into November and December, the UV Index decreases, but vigilance remains essential, particularly as January and February still offer moderate to high exposure risks.
