December is a busy and wet month, but you can still track the herds in the Serengeti.
The November short rains disperse the wildebeest herds across the Serengeti as they head south in preparation for calving season, which kicks off towards the end of the month and lasts through until March. Generally, the main herds may linger in Namiri Plains (just southeast of the central Serengeti region, Seronera) or in Kusini which is towards the southwest of the central area. Some as early as December may have already made it to the fertile Ndutu Plains in the Ngorongoro Conservation Area in preparation for the calving season.
