| January | Shoulder | Southern Serengeti calving begins — half a million wildebeest newborns, predator action concentrated on the Ndutu plains, warm and sunny 28–32°C | Private Ndutu access during calving — fewer vehicles, exceptional predator viewing without the peak-season crowding | 4–6 months |
| February | Shoulder | Calving peak in the southern Serengeti, dramatic light, exceptional photography, moderate crowds | Strong availability at handpicked camps; the year's most intimate predator encounters with private guiding | 4–6 months |
| March | Green | Long-rains onset, dramatic skies, the Serengeti at its greenest, the lowest rates of the year | The most private month of the year — very low crowds, exceptional photography, intimate camp atmosphere | 2–3 months |
| April | Green | Long rains, vivid green landscape, afternoon thunderstorms, some camps close for seasonal maintenance | Solitude and the year's most extraordinary light — operators who know the ground route around closed camps deliver the month well | 2–3 months |
| May | Green | Long rains continue, the Serengeti looks like a different continent — green, lush, photographer's light, very low crowds | The deepest privacy of the year for guests who value solitude above all else; route planning is essential during the rains | 2–3 months |
| June | Shoulder | Dry season begins, the landscape still green from the rains, wildlife starts concentrating at permanent water sources | Classic safari accessibility returns — full northern circuit open, fewer vehicles than peak, excellent camp availability | 4–6 months |
| July | Peak | Grumeti migration corridor active, dry and cool weather, predator concentrations build in the western Serengeti | Private conservancy on Grumeti keeps vehicles off the public-zone traffic; the most refined migration viewing begins | 9–14 months |

| September | Peak | Mara River crossings at their most concentrated, dry and clear, predator activity follows the herds north | Private concession access makes the difference between sharing a crossing and owning one — the month Don plans around most often | 9–14 months |
