As the seasons change, so do ultraviolet (UV) radiation levels, significantly impacting both visitors and residents. January and February experience moderate UV levels (Index 4-5), with a burn time of 30 minutes; caution is still warranted. The UV Index intensifies in March (7), causing a shift to high risk, with a burn time of just 25 minutes. From April to July, UV levels reach extreme heights of 9-11, drastically reducing safe sun exposure to as little as 10 minutes. As we transition into August, September, and October, UV levels remain very high (9-10), with burn times of about 15 minutes. Those months herald high risk, especially for outdoor activities without sun protection. By November and December, UV levels lower back to moderate (3-4), allowing for safer sun exposure again for up to 30 minutes. Advice for everyone: during peak summer months, seek shade, wear protective clothing, and apply sunscreen regularly to minimize the risk of skin damage.
