As the seasons change, so does the UV Index, which indicates the strength of ultraviolet radiation and the potential for skin damage. From January to March, the UV Index remains at a moderate level (3-5), allowing for longer exposure times of about 30 minutes without significant risk of sunburn. However, as April approaches, the UV Index spikes to 8, categorized as very high, and this trend continues through the summer months of May and June, reaching a peak of 10 in July. These months represent the highest risk for sunburn, where just 15 minutes of exposure can lead to skin damage. As summer wanes into August and September, the UV Index begins to decrease but remains in the very high category, emphasizing the need for caution. By October, the risk diminishes to a high level (6), and the burn time increases to 25 minutes, transitioning into the cooler months of November and December, when the UV Index falls to 4 and 2 respectively. Residents and visitors are advised to take precautions, especially during the high-risk months of April through September, by wearing sunscreen, protective clothing, and seeking shade during peak sunlight hours.
