Rain remains frequent early in the month but tapers toward late May; temperatures begin to cool in the highlands. Safari visibility can be lower but rates and crowds are reduced.

Average temperature across Kenya in May.
Mombasa, Diani, Lamu, Malindi
Short-lived but often heavy rains continue into May, then begin to taper; mornings can be humid and warm while afternoons alternate between sun and heavy showers. Diani and Malindi are greener and quieter-great for low-season bargains and birdwatching in the mangroves. Expect fewer daytrippers and slower boat services; bring a waterproof bag and hire boats from reputable operators when seas look unsettled.
Nairobi, Naivasha, Nakuru
The heavy rains taper through May into a wetter-than-usual greenness; mornings can be misty around the escarpments and afternoons alternate between showers and sun. This is an exceptional month for seeing waterfalls higher and rivers running full around Nakuru. Travel remains slower due to soft tracks; pack waterproof boots and expect fewer tourists at the usual viewpoints.
Maasai Mara, Nakuru, Naivasha, Amboseli fringe
May sees the later stages of the long rains with greening plains and swollen streams; early morning fog is common across the lowlands and daytime showers occur regularly. This is low season for safari accommodations, which often offer lower rates, but expect limited accessibility to some remote areas. Pack waterproof boots and be ready for slower transfers between camps.
Nanyuki, Mount Kenya, Aberdare Range
May’s rains taper slowly and the forested mid-slopes are lush, with mossy trails and gushing streams; higher camps can still be wet and cold. Wildlife viewing in Aberdares (bushbuck, elephants) can be good beside rivers, but trail conditions remain soft. For travellers now, favour lower-elevation walks, waterproof boots and guided day hikes rather than multi-day high-altitude climbs.
Kisumu, Homa Bay, Kakamega, Siaya
May sees heavy showers easing toward patchier rains, leaving the countryside intensely green and rivers full-waterfalls and small streams are at their most dramatic. Lake transfer times can be unpredictable and some rural crossings may be impassable after storms. This is a rewarding month for botanists and birdwatchers; bring sturdy boots and plan extra time for journeys between remote spots.
Marsabit, Turkana, Samburu, Isiolo
May often remains variable-some districts get significant rains and a burst of grazing growth while others stay largely dry; pastoralists move livestock in response. This patchiness affects road useability and market access in border towns like Lodwar. For visitors, permits and local advice are essential; be ready for abrupt changes in conditions and schedule flexibility if visiting remote communities.
There are no major festivals or events in Kenya during May to be aware of.
