As the seasons change, so too does the UV Index, significantly impacting outdoor activities. From January to February, the UV levels transition from moderate (5) to high (6), necessitating careful sun exposure planning, especially as burn time decreases from 30 to 25 minutes. March and April see a jump to a very high UV Index of 9 and 10, with corresponding burn times of just 15 minutes, demanding increased sun protection. The most critical months for UV exposure are from May to August, when the index peaks at an extreme level of 12, resulting in an extremely short burn time of merely 10 minutes. Caution is essential during these months, as prolonged sun exposure can lead to serious skin damage. As autumn approaches, September and October maintain a very high status, allowing for 15 minutes of exposure before sunburn sets in again, while November and December drop down to high and moderate levels, respectively. Residents and visitors are advised to stay vigilant during high-risk months, employing protective measures such as sunscreen, hats, and clothing to mitigate UV harm.
