Weather in Argentina
The first thing to remember when planning a trip down to Argentina is that it is in the southern hemisphere, so the seasons are reversed (if you are from the northern hemisphere).
Fall February – March
Winter May – July
Spring August – October
Summer November – January
So no matter where you are planning to travel in Argentina, the hottest months will be around New Years and the coldest will be around mid-year.
U pravu su sto se tice godisnjeg doba u Argentini. Tamo je sada leto. Najveci uticaj na formiranje godisnjih doba ima
ugao pod kojim Suncevi zraci padaju na Zemljinu povrsinu.
http://en.wikipedia.org/wiki/Season
Seasons result from the yearly revolution of the Earth around the Sun and the
tilt of the Earth's axis relative to the plane of revolution. In temperate and polar regions, the seasons are marked by changes in the
intensity of sunlight that reaches the Earth's surface, variations of which may cause animals to go into hibernation or to migrate, and plants to be dormant.
During May, June and July, the northern hemisphere is exposed to
more direct sunlight because the hemisphere faces the sun. The same is true of the southern hemisphere in November, December and January. It is
the tilt of the Earth that causes the Sun to be higher in the sky during the summer months
which increases the solar flux. However, due to seasonal lag, June, July and August are the hottest months in the northern hemisphere and December, January and February are the hottest months in the southern hemisphere.
