Throughout the year, UV radiation levels exhibit significant seasonal variations, peaking in the summer months. From March to August, the UV Index escalates from 7 to 11, indicating increasing risks of skin damage, with July being the highest at an extreme level. April to September are considered high-risk months, where the burn time decreases sharply; for instance, during July, only 10 minutes of unprotected sun exposure can lead to burns. Residents and visitors are strongly advised to take precautions during these months, such as seeking shade, wearing protective clothing, and applying broad-spectrum sunscreen regularly, especially during peak sun hours. Conversely, from November to February, the UV levels drop to a moderate level, allowing for safer outdoor activities with longer exposure times of 30 minutes before risks arise.
