The Balkans can be boiling hot and freezing cold, but neither extreme will prevent travel. In fact, this is a fascinating place to visit at any time of year – even winter. July and August can be uncomfortably hot, particularly in the cities, but this is the time when mountains and beaches are at their best. From a climatic point of view, May, June and September are the best months in which to visit the region, with nowhere too warm or too cool.
