Yeah, speaking from experience too, it's the second coldest African country I've lived in (Ethiopia's frigging cold in winter). Compared to rest of Africa is much cooler in Kenya due to elevated land (for me, relatively anyway, from Southeast Asia, Kenya or at least Nairobi areas, it's really chilly. Right now actually 15 degrees Celcius, which is cooler than most air-conditioned places in SE Asia). Also it seems to be getting weirdly cold there -- 2 years ago massive hailstones destroying crops all around, snow occasionally since mid-2000s. So maybe it's less of an issue there (possibly even slightly more advantageous than in other parts of low-land Africa).
15 degrees sounds really good from the perspective of someone currently baking at 30+ and is thousands of miles away from Kenya. Generally people think that the whole African continent is one big hellish kitchen with a few exceptions, but the southern part of the continent seems to be quite colder than the north and the central part.
Yeah, have to be honest I didn't know much about the world outside until I actually learnt on my own. Geography lessons sort of only served to emphasise film stereotypes. I actually found many parts of Africa cooler and more comfortable to live in than where I come from. I've come to find that temperature is one problem, but also cover (shrubbery, etc.), wind, dust and humidity can sometimes be far more important for comfort and durability of machinery.
Also the issue of humidity mikeywith brought up, very true and that's something we deal with a lot in Southeast Asia, but air conditioning fixes the heat and humidity problem. Something else Kenya does a bit better too that most other parts of Africa (again, because of elevation).
