Indeed, altitude is of relevance in the upper regions of the city. But the cliffs don't offer much of an explanation. Rio is a very mountainous city, crisscrossed by hills that often reach into the ocean (the Sugar Loaf is a prime example). In spring and autumn (each lasting for about a month), it gets chilly up there in the evening (and by chilly I mean 20º C). In the month of winter we experience in mid July, it can get downright cold in the city, specially at night (down to a freezing 13º C). But during the remaining 9 months of the year, we get a mild summer (circa 30º C), except for January, February and March, when temperatures rarely drop below 30º C, and more often than not reach 41º C -- this year we had a few 45º C days). Even at night temperatures rarely drop lower than 30º.MarkB said:Bear in mind that it's a very tall city, and is on cliffs even at its base. Even taking into account whatever dampening effects the manifest zone may have, I'm betting citizens have to take into account a major wind-chill factor.
And here's the thing: Rio surrounds the largest urban forest (talk about an oxymoron) in the world, which covers the largest mountain range in the city. Back in the mid-19th century, that forest was nearly all gone, and temperatures were rising more and more! So the Emperor ordered the forest restored, and the temperatures returned to its usual ranges.
