As the seasons change, so does the UV Index, significantly impacting sun exposure risks for visitors and residents. January and December present low UV levels (Index 2), allowing for safer outdoor activities with a burn time of up to 45 minutes. However, as spring approaches, February sees a rise to moderate levels (Index 4), with burn time reducing to 30 minutes. The risk escalates sharply from March (Index 6) to June and July, where extreme UV conditions (Index 11) align with burn times of just 10 minutes. The late spring and summer months, particularly April (Index 8), May (Index 10), and June (Index 11) signify the highest risk for skin damage. As summer ends, the index gradually decreases, but August and September remain high (Index 9 and 8, respectively) with burn times of 15 minutes. To ensure safety, it is crucial for individuals to take protective measures—such as sunscreen, clothing, and shade—especially during April to August, the peak months for UV exposure.
