As the seasons change, so does the UV Index, significantly impacting sun safety for visitors and residents. From January to February, the UV Index remains at a moderate level (3-4), allowing for 30 minutes of sun exposure without significant risk. However, as we move into March, the index spikes to 7, marking the beginning of high-risk months that peak during the summer. In April and May, the index rises to very high levels (8-10), reducing safe exposure time to just 15 minutes. The extreme levels (11) in June and July necessitate even greater caution, permitting only 10 minutes of safe sun exposure. August and September continue to pose risks with very high levels (8-10) before tapering off in October. By November and December, the UV Index falls back to moderate and low categories (4-2), allowing longer burn times of 30 to 45 minutes. Visitors and residents alike should remain vigilant, especially from March through September, employing sun protection strategies such as sunscreen, hats, and seeking shade during peak hours to minimize health risks.
