As Argentina is in the southern hemisphere, the seasons are the opposite times to when is common in the Middle East. Buenos Aires is a pleasant city all year round but the peak times for travel tend to be spring (September-November) and winter (June-August). The snow sports, such as skiing and snowboarding are popular attractions in the winter, so expect flight tickets to double during those times. Buenos Aires can be hot and humid in the summer, so if you are looking for good times with relative quiet, go in the autumn (March-May). Festivals and sporting tournaments tend to be in these pleasant times during spring and autumn.
