The winter cold snap is back, marking the fleeting “spring” that deceived us for weeks has come to an end.
After an unusually warm period in much of the country, where thermometers recorded temperatures above normal for the season, the Argentinian winter is regaining its dominance with a marked drop in temperatures.
Get ready to dust off your winter clothes, because this week the winter cold is back in full force, especially in the central and southern regions of the country.
A forecasted turn: the incursion of cold air masses
The National Meteorological Service (SMN) has been categorical in its forecast: coats and scarves will once again be essential elements of our attire.

This drastic change in weather will originate from the entry of powerful cold air masses that, starting mid-week, will cause a notable and sudden drop in minimum temperatures.
The days of gentle breeze and soft sunlight will be left behind, giving way to chilly days that will remind us that we are in the midst of winter.
