In Union Progreso, Mexico, understanding the UV Index is crucial for protecting your skin and overall health. With the region's warm Aw climate, local residents and visitors face heightened risks of UV exposure, particularly during midday hours when levels can soar to 15. Being aware of the UV levels helps prevent sunburn and long-term skin damage, ensuring you enjoy the sun safely.
