Average temperature across South Sudan in December.
Juba, Nimule, Kajo-Keji
December delivers the most comfortable, cool mornings and hot but dry afternoons - the classic season for visiting Juba and surroundings. Streets and tracks are firm, domestic travel is reliable and rivers are lower yet still navigable in places. This is the peak visiting window for practical travel: pack light layers for cooler nights, sunscreen for strong sunshine, and insect repellent for dusk along the White Nile.
Torit, Nimule, Imatong Mountains, Kajo‑Keji
December is the highland high season: cool mornings, warm afternoons and stable weather, excellent for summit photography and cultural visits to nearby markets. Mountain accommodations run reliably and guides are available for organized hikes; bring warm layers for nights and sun protection for exposed ridgelines. This is one of the best months to see the Imatong massif on foot while avoiding the mud and river problems of the wet season.
Wau, Rumbek, Raga, Tonj
December is hot and dry, with clear skies and good road access across the western plains - an optimal window for overland exploration and visiting pastoral communities. Daytime heat can be intense, so schedule long journeys for morning and late afternoon, resting in the middle of the day. Bring lightweight clothing, sun protection, and bedding appropriate for warm nights; insect activity is lower than in the wet months but still present around permanent water.
Jonglei, Bor, Pibor, Bentiu approaches
December delivers dry, dustier conditions around the Sudd edges and the White Nile narrows into well‑defined channels that are straightforward to navigate. Villages reopen fuller market schedules after the floods recede, and roads near the river are passable again for vehicles. This is one of the best months for combined river and overland itineraries - bring sun protection, a light jacket for cool mornings, and a strong repellent for dusk.
Malakal, Melut, Bentiu approaches, Nasir area
December returns a consistent dry season with sunny days and cool mornings - excellent conditions for travel in the Upper Nile towns. Roads are generally reliable, air services more predictable, and river navigation straightforward on lower channels. For visitors it’s among the most practical months for exploration; bring light layers for mornings and robust sun and insect protection for riverbank activities.
There are no major festivals or events in South Sudan during December to be aware of.
