Throughout the year, UV index levels vary significantly, with the highest values occurring between January and March, where the extreme exposure category dominates, resulting in a burn time of just 10 minutes. April marks a slight decrease, yet it still poses a very high risk with a maximum burn time of 15 minutes. As we transition into the summer months, the UV index gradually lowers, reaching a moderate level in June and July, allowing for 30 minutes of safe exposure. However, August brings a return to high levels, reverting to a 25-minute burn time. In the fall, September and October again present very high and extreme risks respectively. Finally, the year wraps up with the same extreme UV conditions in November and December, both maintaining a 10-minute burn time. Given these seasonal fluctuations, residents and visitors are advised to be particularly cautious during high-risk months: January to March and October to December, ensuring they use sunscreen, wear protective clothing, and limit sun exposure during peak UV hours.
