As the seasons change, so does the UV Index, which indicates the potential for skin damage due to sun exposure. From January to March, the UV levels are moderate, with an index ranging from 3 to 5 and a burn time of 30 minutes. However, as we transition into April and May, the index climbs sharply, peaking at 8 in May and marked as very high, reducing burn time to just 15 minutes. The months of June and July are particularly concerning, maintaining a UV Index of 10, signifying extreme exposure risk. Even August remains high at 9, before tapering off in September and October to a high of 7 and 6, respectively, where burn times increase back to 25 minutes. The winter months of November and December see much lower UV levels, with indices of 3 and 2 and extended burn times of 30 and 45 minutes. Residents and visitors should take extra precautions during the high-risk months of April to August, applying broad-spectrum sunscreen, wearing protective clothing, and seeking shade during peak hours to minimize sun damage.
