With a climate characterized by tropical warmth and ample sunshine, awareness of UV levels can play a significant role in preventing sunburn and protecting skin health.

Throughout the year, UV index levels exhibit significant seasonal fluctuations, with the highest risks occurring in the winter months of January to March and again in late fall, particularly in November. During these periods, the UV index remains at an extreme level of 16, indicating a burn time of just 10 minutes, making these the highest-risk months for sun exposure. As spring progresses, the UV index gradually decreases, ranging from 12 in April to 7 in June, but caution is still advised, especially in late spring and parts of summer when it reaches 9 in May and peaks again at 8 in July and 10 in August—both classified as very high risk. Autumn sees a return to extreme levels in September, October, and again in November. Residents and visitors are strongly encouraged to protect themselves during these high-risk months, seeking shade, wearing protective clothing, and applying sunscreen diligently to minimize UV exposure.
