Throughout the year, UV exposure varies significantly, with the highest risk occurring during the late spring and summer months. March through October sees notably elevated UV Index values, reaching an extreme peak of 12 in July and 11 from May to September. The high-risk months are therefore May to September, where a burn time of just 10 minutes is sufficient for skin damage under extreme conditions. During these periods, it is crucial for residents and visitors to take precautionary measures: seek shade, wear protective clothing, and apply broad-spectrum sunscreen regularly. Conversely, in the cooler months of January and December, the UV Index drops to 4, indicating a moderate risk where exposure is less critical, but protective measures should still be practiced on sunny days. Staying informed about these seasonal UV changes is vital for maintaining skin health throughout the year.
