Weather in Nakuru in September

A good month. September is a solid month to be in Nakuru. You should expect rain on 18 days of the month, which is more days wet than dry.

September ranks 4 of 12 in Nakuru: past the worst of the year but short of January, which is the month to book if the dates are open.

This is persistent light rain rather than storms: 18 wet days but only 1 heavy ones. It rarely cancels anything outright, and it rarely fully clears either. A jacket beats an umbrella. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.

What the averages hide

Averages flatten a month, and this one hides a few things: it never really gets hot: not one day in an average September reaches 30 °C. Across the twenty years measured, the hottest September day reached 29.9 °C and the coldest night fell to 9.8 °C, and the wettest single day dropped 66 mm — roughly 78% of the month's rain in one day.

September is moderately variable: 33 mm in the driest year against 213 mm in the wettest, around an average of 85 mm. Roughly two Septembers in three land near that average, and the third does something else entirely.

Wind is light at 6.9 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 75%, high enough to notice on the warm days without dominating them.

How September sits in the year

Temperatures hold steady either side: 23.9 °C in August, 25.1 here, 25.5 in October. Nothing about the timing within the month matters much.

Daylight in September

Nakuru sits close enough to the equator that daylight barely moves all year — 12.1 hours in September, against a range of just 0 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: 15.3 °C between the year's warmest afternoons and coldest nights. At 1802 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

Quiet. Few other visitors, cheaper rooms, and a real chance some seasonal operators are shut.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

September in Nakuru versus nearby

If Nakuru is one option among several, the nearby comparison is worth making. Nairobi is a better bet in September — 3.3 °C warmer, 12 days less rain. Kakamega is close enough to be a coin toss — within a degree on temperature, 8 days more rain.

So: September works, with January the better month by 13 points if the dates can move. If they cannot, nothing here should stop you booking.
