As the seasons change, so do the patterns of UV exposure, with significant increases typically observed from March through September. The high-risk months for UV exposure are April through September, when the UV Index often reaches very high to extreme levels, particularly peaking in June at an Index of 11. Residents and visitors should be particularly cautious during these months, as the potential for skin damage increases dramatically; burn times can drop to as little as 10 minutes in June. To protect yourself, it's recommended to apply sunscreen regularly, wear protective clothing, and seek shade during peak sun hours. From October to February, the UV levels decrease significantly, with burn times extending back to 30 minutes in January and November, making outdoor activities safer, but still requiring some level of UV protection during sunny days.
