Specifically, April, May, June, July, August, and September showcase very high to extreme levels, with June posing the greatest danger. It’s imperative for residents and visitors to take precautions during these months. Sunscreen application, protective clothing, and limiting exposure times, especially during midday when the sun is strongest, are vital measures for staying safe from UV-related harm.
