Serengeti in May

Where the herds are in May

May is the migration in full flow. Having left the southern calving plains behind, the herds spend the month streaming north and west through the central Serengeti's woodlands and onto the Western Corridor, drawn toward the Grumeti River — the migration's first major water test of the year. In a typical year the leading columns are well into the western reaches by late May, strung out in long, dramatic lines across the country.

It is one of the most evocative chapters of the loop: tens of thousands of animals on the move, often in single-file columns miles long, with bull wildebeest beginning to spar as the rut stirs late in the season. But it is also fluid — the precise position depends heavily on the rains, and the herds can be spread across a large area in transit. Treat May timing as a long-term average and confirm the live picture for your exact dates before you commit to a sector.

May at a glance

A quick frame for planning the transition month. Set expectations, then verify the migration's live position, conditions and current fees before booking.

• Migration: streaming north and west toward the Grumeti and Western Corridor (30-year average; verify).
• Weather: long rains tapering through the month toward the dry season; greener early, drier late.
• Wildlife: dramatic moving columns, the early rut, resident game reliable in the centre.
• Crowds & value: still quiet and good value early; rates begin to firm as the dry season nears.
• Best for: flexible travellers, photographers of herds on the move, value-seekers ahead of the peak.
• Best sector to base in: central Seronera early, shifting toward the Western Corridor late month.

Weather: the rains taper

May usually marks the easing of the long rains. Early in the month can still be properly wet, a continuation of April's pattern, but as the weeks pass the storms tend to thin out and the long dry season begins to take hold — drier, clearer and firmer underfoot by late May in most years. It is a genuinely transitional month, and conditions can swing from one week to the next.

That makes May a rewarding gamble for travellers who value greenery and quiet over certainty. The plains are still lush, the air washed clean, vehicle numbers low, and the light often superb as skies clear. Pack for both worlds: waterproofs and warm layers for cool, damp early-month mornings, plus dust protection for the drier, brighter days that follow. As always, none of this is guaranteed — May is the month the Serengeti changes its mind.

Following a moving migration

Watching the migration in transit is a different pleasure from a river crossing or the calving plains. There is no single set-piece to wait for; instead the reward is scale and movement — endless columns of wildebeest and zebra flowing across the land, the dust and noise of a herd on the march, the early sparring of the rut. For photographers, the long lines of animals under big transitional skies make for some of the most evocative imagery of the whole year.

Because the herds are spread and shifting, basing yourself well matters more than usual. Central Seronera is a strong, all-weather anchor early in the month, with the option to lean west toward the Grumeti and Western Corridor as the columns advance later in May. Resident wildlife in the centre — lion, leopard and a full cast of plains game — keeps the game viewing reliable even when the migration is between landmarks. Sightings are never promised, and a guide who can read the herds' direction of travel is invaluable in a transition month.

Value, planning and combining

May still carries much of the low season's appeal: quiet plains and good value early on, with rates beginning to firm as the dry-season peak approaches toward month-end. For travellers who can stay flexible, it is one of the year's smartest windows — green-season character and prices with the dry season on the horizon. Keep your itinerary adaptable so you can follow the herds north and west, and confirm camp positions against the migration for your exact dates.

May combines well with the Northern Circuit, and easing rains make the overland legs through Ngorongoro and Tarangire less of a gamble than in April, though early-month roads can still be heavy — allow some buffer or lean on flights. A Zanzibar beach finish makes a fine contrast. Park fees, conservation levies and camp rates change over time and some seasonal camps are still reopening after the rains, so confirm openings and current figures with official and operator sources rather than relying on quoted numbers.
