Traveller notes on Nairobi in October
Other months in Nairobi
Regulars are specific that November's short rains typically start easing by mid-month, this stretch marking a genuine turn toward plenty of sunshine without yet tipping into properly hot - regulars call this among the more enjoyable months for exactly that combination. Our row backs that warm, still-showery read, 26C over 15.7C nights, with 47.8mm of rain across 8 days and humidity at 71 percent. Regulars are consistent this counts as traditionally the start of the region's warmer stretch, evenings still cool enough at this elevation for a light layer even as days turn pleasant. A rain jacket remains worth packing for the tail end of the short rains rather than relied upon as a given. The record: 10.8 hours of sun, a 17 kph wind and AQI 47.
Regulars call July part of Kenya's winter and its best travel season at once - dry, cooler than the rest of the year, and the more expensive stretch for exactly that reason. The catch they name every time is the morning: mild warm days give way to properly cold nights and dawns, overcast and damp more often than not, needing a real jacket or fleece rather than a light layer. Our row backs both halves, 23.3C reading as 23C over 12.9C nights, with rain almost gone at 16mm across 4 days. This is also safari season at altitude rather than at the coast, so the chill belongs to Nairobi and the highlands rather than to Kenya as a whole. The record: humidity 67 percent, 8.3 hours of sun, a 10.7 kph wind and AQI 71.
Regulars keep correcting the same assumption: this city is cooler and drier-feeling than the rest of Kenya because it sits high, so June here is not an equatorial month. They give low to mid 70s by day, cool mornings and evenings, and days that can stay at 16 to 18C - our row reads 23.7C over 13.6C at 70 percent humidity. June also runs towards July and August, the coldest part of the year. Their packing list is a spring one: a light rain jacket, a fold-up umbrella and a fleece for the evening. Rain is modest at 35.2mm across 6.8 days. The figure worth knowing is the air, at AQI 81. The record: 9.8 hours of sun and an 11 kph wind.
September sits inside Kenya's dry season, with little and possibly no rain before the short rains arrive in late October - our row gives 25.9mm across 4.7 days at 63 percent humidity. Regulars describe mid-September to mid-October as dry and warming, with Nairobi's own weather picking up through the month, and one benefit they mention unprompted: the mosquitoes are largely out of season. The standing warning is about the ends of the day rather than the middle - early morning and sunset game drives get genuinely cold in an open vehicle, which our row's 13.9C night under a 26.3C day explains. Layers, always. The record: 10 hours of sun, a 13.8 kph wind and AQI 53.
