How often does it rain in Nairobi?
Nairobi records around 899mm of rain a year, spread across about 154 days — roughly 42% of all days, or 13 days in an average month. In practice that makes rain a regular feature of running in Nairobi rather than an exception — close to one day in two. A decent waterproof and a peaked cap earn their place in the kit bag year-round.
The wettest month is April, averaging 186mm across about 26 rainy days. The driest is July, with 20mm over roughly 5 days. Even in July, average lows stay around 12.6°C, so cold is rarely the limiting factor here. Summer highs peak around 27.4°C in February, comfortable for most daytime running.
Those are ten-year averages, not a forecast. What actually matters on the day is the next twelve hours — which is what the live verdict and hourly strip at the top of this page are for.
