Throughout the year, UV Index levels exhibit significant seasonal variations, with the highest risks occurring during the spring and summer months. From March to September, the UV Index consistently remains at high to extreme levels, with the most critical months being June and July, where the UV Index peaks at 11 and 10, respectively. During these periods, the recommended burn times are notably short, ranging from 10 to 15 minutes, indicating a high likelihood of skin damage with unprotected exposure. Conversely, the winter months of January and December present low UV levels (Index 2), allowing for longer sun exposure (up to 45 minutes) without significant risk. To protect against harmful UV exposure, visitors and residents are advised to apply broad-spectrum sunscreen, wear protective clothing, and seek shade, particularly during the high-risk months from April to August.
