"How is the weather in Autumn? it is cold? The swimming pools are open?"
It's very trivial to say that the temperature in the world is changing and getting warmer, but it's a truth. Since 2011 I can recognize the changes in weather and every year the season is getting longer, and late September and October are warm months: of course, during the night the temperature goes down, in these days We have 6 degrees, but during the day it goes to 25..
From the "touristic" point of view this is very positive, but it can be a real problem for the agricultural business... anyway, have a look at this short video... it gives an idea..
