Let´s talk about weather in Buenos Aires.
Buenos Aires (Bs. As.) is a beautiful city where you can do a lot of things, but even if Buenos Aires is not usually that has extreme conditions, in specific situations the weather can be a bit complicated.
For example, now we are in summer and the average high temperature is approximately 30º C ( 86º F), but the problem is not the temperature, the problem is what it feels like. If it felt like the actual temeratue there would be no problem, but when it feels like it is over 38º C (100º F), you feel like there is no oxygen and you begin to sweat. That is, because in Buenos Aires it is common to have high humidity and this makes that those days will be very hot and humid. So the only thing you want is to stay at home or in a place with an air conditioner, but never to walk in the street.
But the same thing happens in winter!! So if you are planning to visit Buenos Aires be careful with the extreme weather conditions.
