The UV Index experiences significant fluctuations throughout the year, with the most intense exposure occurring from March to October. April typically sees the highest peak at a UV Index of 15 and is classified in the extreme exposure category, alongside the summer months of July and August, which register a UV Index of 13-14. Visitors and residents should be particularly cautious during these months, as the burn time is reduced to just 10 minutes. January and February also present high UV risks, with categories labeled as very high and extreme, necessitating protective measures. To minimize the risk of UV exposure, it is advisable to wear sunscreen, protective clothing, and sunglasses, particularly during midday hours when UV intensity is at its peak. As the year winds down, the UV Index moderates, falling to a 9 in December, which still warrants attention for skin protection but indicates a lower risk compared to the spring and summer months.
