Climate & Altitude
Nairobi's high-altitude equatorial climate is one of its most appealing features for expats from temperate countries — perpetual spring with minimal humidity and no need for air-conditioning for most of the year.
- Altitude: 1,795m above sea level — significantly cooler and less humid than coastal East Africa
- Daytime temperatures: 18–26°C year-round; rarely below 12°C at night or above 28°C
- Long rains: March–May (heavier); short rains: October–December (lighter)
- Dry and sunny: January–March and June–September — the most pleasant months
- No air-conditioning needed for most of the year in Nairobi; ceiling fans are usually sufficient
- Altitude adjustment: most people feel no effect, but mild headaches in the first few days are possible if coming from sea level
