Average temperature across Benin in December.
Cotonou, Porto‑Novo, Grand‑Popo, Ganvié
December settles into the dry season with pleasantly warm days and much drier air brought by the harmattan wind later in the month; evenings can be noticeably cooler than the humid months. Holiday travel picks up, especially around Cotonou and Porto‑Novo, and coastal resorts see more visitors - book ahead. Sunscreen and breathable layers are enough for most days, and the clearer skies make port and lagoon photography excellent.
Abomey, Bohicon, Dassa‑Zoumé, Cové
December settles into the dry, warm season with clear skies, cooler nights and firm roads - ideal for visiting museums and the royal palaces of Abomey. The harmattan can increase dust on some days, especially away from forested areas, but daytime touring is very comfortable. This is a popular time for local events and for combining cultural itineraries with short hikes in the Collines.
Natitingou, Atakora Mountains, Pendjari National Park
December settles into the dry season with clear skies, cool nights on the ridges and dusty afternoons in the plains; the Harmattan can reach the highlands but is less intense than on the coast. Pendjari’s wildlife viewing is at its most reliable as animals gather at permanent waterpoints, and park infrastructure is fully operational. Early bookings are wise around holidays, and bring warm clothing for pre‑dawn game drives.
Kandi, Malanville, Karimama, and the Niger border
December is firmly dry and hot by day with crisp mornings and the first hints of harmattan dust possible late month; the Niger is low and riverside life slows into the dry season rhythm. Travelling is straightforward on sealed roads, and the skies are clear for landscape photography. Pack for heat during the day but bring a warm layer for cooler evenings away from the river.
There are no major festivals or events in Benin during December to be aware of.
