Given the size of Argentina you should anticipate a variety of climates along your travels. In fact, the hottest and coldest temperature extremes of the South American continent are known to have occurred in Argentina with the highest temperature ever recorded having reached 52.8ºC and the lowest being -40ºC. What is important to know are which months you should expect which season to occur when travelling to Argentina so that you can be prepared with the best type of clothing for your trip. So here it is - Spring occurs during the months of September – November; summer occurs during the month of December – March; autumn takes up the months of April and May; whilst winter conditions are experienced from June – August.
If we divide Argentina into three main regions, northern, central and southern Argentina it becomes easier to determine what types of weather conditions you should prepare for:
The north of Argentina, which is situated in and below the Tropic of Capricorn, is highly characterized by hot and humid conditions which are why swamp lands are found in this particular part of the country. The summer season which experiences temperatures averaging close to 30ºC, can become quite tiring if you're not used to higher temperatures in your own country. Winters are certainly not cold and wet, instead being mild and dry with periodic droughts known to occur.
Central Argentina has a much more varied climate which is particularly good for agriculture. In fact the richest and most fertile soils of the country are found exactly here. Winters are cool with the possibility of some snowfall and summers are predominantly hot, however, occasional tornadoes and thunderstorms are known to occur; especially towards the west which is famous for producing the largest-sized hailstones ever recorded.
As you work your way towards southern Argentina, you will feel temperatures a lot cooler but this is no surprise as Argentina's most southern points are greatly influenced by Antarctic conditions. Summers are mild with average temperatures of only 9ºC although some areas can experience much higher temperatures but these are known not to be too long-lasting. Winters are very cold with plenty of heavy snowfall on offer. Temperatures will drop dramatically in mountainous areas and at elevated grounds.
