May vs July

Strong option

Long Rains tapering — Diani Coast starts to look attractive and Mara is still difficult.

• ↑May sees the Long Rains begin to taper from their April peak. By mid-to-late May, sunny windows become longer and more frequent. This is an excellent time to visit the Kenyan coast — Diani Beach and Watamu are transitioning from the hot, calm season toward the arrival of the SE trade winds. The sea is warm (27°C), reefs are visible, and accommodation prices are at their annual coast lows.
• ↑Kenya's tea country around Kericho (the largest tea estate region in Africa) is at its most lush and intensely green in May, with the rolling hills of the Rift Valley escarpment looking implausibly photogenic. A drive from Nairobi to Kericho and back via the Rift Valley viewpoint is one of the country's great scenic routes.

Best match

The Great Migration peaks — 1.5 million wildebeest and the most spectacular river crossings.

• ↑July is the month Kenya exists for in the global travel imagination. The Great Migration river crossings begin in earnest: the Mara River crossing points — Crossing No. 1 in the Mara Triangle, Lookout Hill, and the Serena crossing — host wildebeest plunging into the river in groups of thousands, with Nile crocodiles (some over 5 metres long) intercepting the herd mid-water. A single crossing event can last 2–4 hours and involve 50,000–200,000 animals. There are no guarantees on timing — crossings occur based on wildebeest instinct and predator pressure — but July is the peak month for crossing frequency.
• ↑The Maralal International Camel Derby (typically late July, Maralal town in Samburu County) is one of East Africa's most extraordinary cultural and sporting events — amateur and professional camel racing drawing participants from across Kenya and internationally. The surrounding Samburu landscape, distinct from the Mara, hosts elephants, reticulated giraffes, and Grevy's zebra.
