Temperature in Nairobi in January
The 12°C day-night temperature range is typical for continental climates: a light jacket in the morning that you shed by midday and need again after sunset.

Wind averages 17 km/h, light enough to be refreshing on warm days but noticeable in open coastal areas or elevated viewpoints. In Fahrenheit: 79°F average high, 57°F overnight low.

Packing for Nairobi in January means dressing for 26°C days and 14°C evenings. A light cotton tee with a casual overshirt works well at 26°C, the overshirt doubles as a layer for air-conditioned venues. Evenings drop 12°C to around 14°C, a notable shift that catches underprepared visitors off guard. Pack a dedicated evening layer. Comfortable walking trainers are the versatile choice for both outdoor sightseeing and indoor venues. At 82% average humidity, quick-dry synthetic or bamboo fabrics dry overnight and stay comfortable longer than cotton.
Local tip: Layers are more practical than a single heavy garment in Nairobi. The day-to-evening temperature shift rewards packing a versatile mid-layer you can add or remove as conditions change.

Why is Nairobi warm in January?
Nairobi's January climate is governed by the Inter-Tropical Convergence Zone (ITCZ), which draws moisture-laden trade winds across the region, producing the characteristic wet season rainfall of warm tropical cities. Daytime heat peaks around 26°C, moderated slightly by afternoon convective showers. Overnight temperatures remain warm at 14°C because the humid air retains heat effectively. Climate data: Open-Meteo ERA5 (1991–2020).
Sunshine Hours
The average number of hours per day with direct sunlight. Calculated from satellite measurements. Days with more than 7 hours of sunshine are ideal for outdoor activities. Under 3 hours means overcast conditions dominate.
UV Index
A scale from 0-11+ measuring ultraviolet radiation intensity. UV 0-2: Minimal risk. UV 3-5: Moderate, wear sunscreen. UV 6-7: High, hat and SPF 30+ essential. UV 8-10: Very High, limit midday exposure. UV 11+: Extreme, seek shade between 10am-4pm.
Rain Days
A rain day is counted when precipitation exceeds 0.1mm. This threshold captures even light drizzle. Unlike total rainfall in mm, rain days tells you how often you might need an umbrella, which is useful for planning outdoor activities.
