Understanding the UV Index in Jongiyeh, Iran is vital for safeguarding your skin and promoting overall health in this sun-drenched region. The UV Index provides crucial information about the intensity of ultraviolet radiation during the day, helping residents and visitors alike to take appropriate sun protection measures. In Jongiyeh's dry, semi-arid climate, average UV levels can spike significantly—reaching as high as 10 during midday, when the risk of sunburn and long-term skin damage escalates.
