Throughout the year, the UV Index shows significant seasonal variation, with the highest levels occurring from February to September. The most critical months for UV exposure are February, March, April, May, July, and August, where the UV Index consistently reaches extreme levels (above 11) with a burn time as short as 10 minutes. Visitors and residents should take precautions during these high-risk months by seeking shade, wearing protective clothing, and applying broad-spectrum sunscreen frequently. As the year progresses into the later months, while the UV Index decreases slightly, it is still advisable to remain vigilant, especially in November and December when the UV levels are at very high (9) and high (8), respectively, as 15-minute burn times can still pose a risk.
