Buenos Aires is never a bad place to visit. There is a constant flow of tourist traffic to Buenos Aires all year round, with of course few upward spurts and some downward spirals. December to February (summer) is a good time to board flights to the city for those who wish to avoid plummeting temperatures in the northern hemisphere. July to August (winter) is another high season with the advent of South American ski season. Of course, cheap flights are hard to come by during these peak tourist periods, especially around the Easter and New Year's. For a budget trip, consider booking tickets for a holiday during spring (September to November) and autumn (March to May). These are the times when cheap flights and accommodation are readily available.
