South Sudan has a rainy season witch lasts from
may to November. The rainy season massively limits roads and other transportation due to south Sudan's roads being dirt tracks and in the rainy season they turn into mud tracks. The only paved roads South Sudan has are in major cities like Juba and Rumbek. The 190 Kilometers from Nimule on the Ugandan Border to Juba has recently been paved. Work is underway to upgrade the road from Juba to Bor.
