Traveller notes on Serengeti in December
Notes from nearby Maasai Mara (107 km away)
Serengeti doesn't have its own notes for December yet — these are about Maasai Mara, close enough to share the season.
Forum posters describe December as hot with short showers - typically late afternoon into the evening, sometimes clearing entirely by Christmas as November's short rains ease off. Posters are consistent this isn't heavy enough rain to wash out game drives, and the reserve's resident wildlife stays reliably visible even without the Great Migration herds present this time of year (migration is a July-October event). The clear downside: late December is genuinely peak season, with Christmas, Boxing Day and New Year's Eve supplements pushing rates noticeably higher and camps filling up well in advance. Overall posters rate December a strong, dependable time for a safari despite the seasonal price premium.
Other months in Serengeti
Serengeti-forum threads on an April visit describe rain as genuinely not something that scares off the animals, posters naming this a real reason April still works well despite being deep in the wet season. Regulars call migration herds genuinely on the move by April, several posters naming a shift into the western-central Serengeti as calves from the earlier calving season grow stronger. Posters call the actual calving genuinely finished by this point, several regulars naming late January through early March as the real calving window rather than April. Regulars call warm days with afternoon thunderstorms a standard pattern, several threads naming a green, uncrowded landscape as the payoff for visiting during the rains. Posters recommend real flexibility around migration location in April, several regulars calling this standard given how much herd movement depends on where rains are heaviest. The record: 27.1C days, 16.7C nights, 122.1mm across over 15 days and 69 percent humidity.
Serengeti-forum threads on a May visit describe mid-May as the tail end of the long rains, posters calling showers still possible though usually short rather than lasting a full day. Regulars call the landscape genuinely lush by late May, high green grasses, trees in leaf and wildflowers scattered across the plains and crater floor. Posters call the migration herds typically found in the western corridor this month, though exact positioning shifts year to year depending on rainfall. Regulars call May a real value window, considerably fewer tourists and better lodge rates than the peak dry season draws. Posters recommend a strong guide as genuinely essential this month, several regulars calling guide quality the real determining factor for how much wildlife gets seen in May specifically. The record: 27.2C days feeling like 28C, 16.3C nights, 31.2mm across nearly 6 days and 61 percent humidity.
Serengeti-forum threads on March timing describe this as still genuinely strong for the Ndutu calving season, posters calling early March a real continuation of February's peak with plenty of calves and predator action still concentrated in the area. Regulars call location the biggest variable this late in the window, the herds beginning to shift depending on rainfall and where fresh grass comes up. Posters describe a typical March shower as a brief, dramatic afternoon thunderstorm or a light overnight system rather than an all-day soak. Regulars call the tall grass a real downside for spotting smaller animals, though it does concentrate wildlife along the roads. Posters recommend a guide with current knowledge of herd movement rather than assuming a fixed location holds. Regulars call March genuinely rewarding for anyone specifically chasing the calving spectacle. The record: 28.7C days feeling like 30C, 17C nights, 83.2mm across nearly 11 days and 60 percent humidity.
Serengeti-forum threads on September visits describe this as sitting solidly within the dry season, clear and sunny days the norm though posters call mornings and evenings genuinely chilly, warm layers essential for early game drives regardless of how warm the afternoon runs. Regulars call September noticeably cooler than October or April, several posters describing sweaters for dawn drives and a fleece worth keeping on hand around the crater rim. Posters describe the herds as generally starting their crossing back from the Mara by late September, dust also picking up, worth keeping gear covered. Regulars are direct any real system this early is genuinely unpredictable, some years seeing almost nothing through the month. Posters call September a reliably strong month despite the cool mornings. Regulars recommend real layers rather than assuming based on the warm midday temperature. The record: 29.5C days feeling like 30C, 16.9C nights, a low 45 percent humidity and 10.6 hours of sun.

- Rule
Park permits run 24 hours
1 Jan – 31 DecBook earlyThe conservation fee is valid for twenty-four hours from entry and the rangers check on the way out; overstaying buys another full day, and a day-trip permit is shorter again. It is why itineraries are built around gate times, not sunsets. Source ↗
- Season
Short rains
1 Nov – 15 Dec · usuallyMonsoonA month or so of afternoon showers that green the plains and knock five months of dust out of the air. The herds drift back south through it, the park is quiet, and the light is the best of the year for photographs.
- Nature
Migrant birding season
15 Nov – 15 Apr · usuallyBirdlife seasonEuropean and Asian migrants arrive with the short rains and stay until April, on top of the residents in breeding plumage. The wet months are the ones birders choose and the game drivers avoid.
- Holiday
Christmas and New Year peak
