Köppen Climate Classification and Nairobi’s Unique Climate
Nairobi’s weather stays mild all year, thanks to its elevation and equatorial location. Rainfall, temperature, and sunshine combine to give the city a climate that’s pretty different from other African capitals.
Overview of Nairobi’s Climate Type
According to the Köppen climate classification, Nairobi usually falls under Cfb (oceanic climate) or sometimes Cwb (subtropical highland climate), depending on who you ask. Both types mean moderate temperatures, no extreme dry season, and clear rainy periods.
The yearly average temperature sits close to 18–20°C (64–68°F). Highs reach the mid-20s °C (mid-70s °F), and lows settle around 12–14°C (54–57°F).
Because the temperatures don’t swing wildly, you don’t get those sudden changes common in lower regions.
Rain falls throughout the year, but it peaks in April–May and October–November. December, when Christmas rolls around, usually brings lighter showers than the long rains, with totals near 50–60 mm. So, you’ll see some rain, but you’ll also get long stretches of dry, clear weather.
Humidity averages between 65% and 80%, and it feels comfortable compared to the coast. December brings about 9 hours of sunshine per day, so there’s plenty of daylight for outdoor activities, even if clouds drift by.
How Geography Influences Christmas Weather
Nairobi sits at about 1,795 meters (5,889 feet) above sea level. This altitude really shapes your Christmas weather.
Even though the city’s almost on the equator, the high elevation keeps daytime temperatures mild and nights cool.
The highlands and nearby mountains influence rainfall, too. Moist air from the Indian Ocean rises over this terrain, causing showers, especially in the wet seasons.
In December, this effect weakens, so you get fewer rainy days compared to April or November.
Nairobi escapes the extreme heat of Kenya’s lowlands and the heavy humidity of the coast. Instead, you get daytime highs around 24–25°C (75–77°F) and cooler nights close to 14°C (57°F).
These conditions make outdoor gatherings, safaris, and city walks genuinely comfortable during the holidays.
Winds stay gentle, averaging about 11 km/h (7 mph), which keeps the air fresh without any bothersome gusts. This mix of warmth, manageable rainfall, and steady breezes really defines Nairobi’s Christmas climate.

Rainfall averages around 58 mm, which is much less than the heavy April rains but still enough to keep things green.

Humidity stays moderate, often between 70% and 80%. Paired with some rain, the air can feel a bit damp.
But with fewer rainy days than November, it’s much easier to get out and about.
This transition means you avoid the heaviest rains but still get cooler, comfortable weather compared to the hotter months.
Day and Night Temperature Variations
December temperatures remain mild, making Nairobi comfortable for both visitors and locals. Daytime highs usually range between 24°C (75°F) and 26°C (79°F), so afternoons feel warm but not too hot.
