Weather in Nairobi in October

A good month. October is a solid month to be in Nairobi. Highs average 28.6 °C, lows 14.3 °C, and rain falls on 14 days — nothing in the month is working against you.

October ranks 10 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: October is the weakest month of Nairobi's year and it is still a perfectly good one. The downside here is small.

This is persistent light rain rather than storms: 14 wet days but only 1 heavy ones. It rarely cancels anything outright, and it rarely fully clears either. A jacket beats an umbrella. Pack for 28.6 °C days and 14.3 °C nights; the spread matters more here than any single number.

What the averages hide

Averages flatten a month, and this one hides a few things: 8 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest October day reached 32.4 °C and the coldest night fell to 11.6 °C, and the wettest single day dropped 26 mm — roughly 49% of the month's rain in one day.

October is moderately variable: 15 mm in the driest year against 137 mm in the wettest, around an average of 53 mm. Roughly two Octobers in three land near that average, and the third does something else entirely.

Wind is light at 12.9 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 62%.

How October sits in the year

Temperatures hold steady either side: 28.4 °C in September, 28.6 here, 26.8 in November. Nothing about the timing within the month matters much. Rain is the thing that moves: November brings 7 days more of it, so the earlier half of a flexible trip is the safer half.

Daylight in October

Nairobi sits close enough to the equator that daylight barely moves all year — 12.1 hours in October, 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. Within October itself the daily swing is 14.3 °C, so mornings and afternoons need different clothes.

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.

October 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 — 3.1 °C cooler, 8 days more rain. Kakamega is close enough to be a coin toss — 2.8 °C cooler, 12 days more rain.

So: October is a compromise. July is 25 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.
