Understanding the UV Index is crucial for the residents of Haraat, Mongolia, as it plays a key role in safeguarding skin health against harmful sun exposure. With peaks reaching a high of 9 during midday hours, awareness of UV levels is essential for preventing sunburn and long-term skin damage. Haraat's semi-arid climate (BSk) means that even on mild days, the sun can emit intense UV radiation, especially during summer months.
