Best Time
In order to avoid both the winter cold and the summer heat, the
best times to visit Graz are spring and autumn, and in particular, the months of May, June and September: daytime temperatures are pleasant, although it's better to bring a sweater and a jacket for the evening. In July and August, the temperature is usually not too hot, however, there is the risk of some very hot days, which can happen, though more rarely, also in the second half of June and in the first half of September.
