As the seasons change, so do the UV levels, which can significantly impact outdoor activities. From January to February, UV Index levels remain low (1-2), offering extended burn times of 45 minutes. March and April see a rise to moderate levels (5), reducing burn time to 30 minutes. May marks the onset of high UV levels (7), with burn times decreasing to 25 minutes. The peak months of June (8) and July (7) experience very high to high UV exposure, shortening safe sun exposure to just 15-25 minutes. August (7) and September (6) continue high levels; residents and visitors should be vigilant as burn times remain around 25 minutes. In October, conditions drop back to moderate (3), allowing for 30 minutes of exposure before returning to low levels in November (2) and December (1), where safe burn times return to 45 minutes. Therefore, during the high-risk months of May through September, it is crucial to practice sun safety by wearing sunscreen, protective clothing, and limiting direct sun exposure during peak hours.
