Weather in Nairobi in April
Kenya · 20-year averages, April
A good month. April works. It is not the peak, but nothing about it fights you. You should expect rain on 21 days of the month, which is more days wet than dry.
April ranks 12 of 12 — near the bottom of Nairobi's year. July is the month that works, and the swing between the two is 30 points, which is a different holiday rather than a slightly better one. Worth keeping in perspective: April is the weakest month of Nairobi's year and it is still a perfectly good one. The downside here is small.
Rain on 21 of the month's 30 days, 3 of them heavy. At that frequency a wet-weather backup is not a contingency, it is the itinerary — book the indoor things first and treat the clear days as the bonus. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.
What the averages hide
The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest April day reached 32.9 °C and the coldest night fell to 11.9 °C, and the wettest single day dropped 38 mm — roughly 33% of the month's rain in one day.
April is moderately variable: 35 mm in the driest year against 214 mm in the wettest, around an average of 114 mm. Roughly two Aprils in three land near that average, and the third does something else entirely.
Wind is light at 10.5 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 73%.
How April sits in the year
Temperatures hold steady either side: 29 °C in March, 27.2 here, 25.8 in May. Nothing about the timing within the month matters much. Rain is the thing that moves: May brings 6 days less of it, so pushing the dates later buys drier weather.
Daylight in April
Nairobi sits close enough to the equator that daylight barely moves all year — 12.1 hours in April, against a range of just 0.2 hours across the whole calendar. Sunrise and sunset land at roughly the same time whenever you come.
An inland climate
Despite being inland, the year stays fairly even: 16.9 °C between the year's warmest afternoons and coldest nights. At 1684 m, altitude is doing as much work here as latitude: thinner air means fierce sun by day and heat that leaves the moment it sets.
How busy it gets
Off season. The genuine off season: cheapest by a distance, with the caveat that some tours and restaurants close entirely.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
April in Nairobi versus nearby
If Nairobi is one option among several, the nearby comparison is worth making. Nakuru is close enough to be a coin toss — within a degree on temperature, 3 days more rain. Kakamega is close enough to be a coin toss — within a degree on temperature, 2 days more rain.
So: April is a compromise. July is 30 points better and is what Nairobi is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
