June-August, September and October is the best time to visit Austria. Austrian summers are comfortably warm and not too prickly hot. It’s a good time for having a good time outdoors. The streets are filled with travellers from all over the world during these months, and hence, accommodation costs are higher. There’s a rush of tourists in all famous places. The average temperature in June-August remains 25°C (77°F). August is the best month of swimming, biking and hiking, which also sees around 7-8 days of rainfall, which, however, won’t be a barrier for you in your exploration. To experience the best of Austria’s wine culture, September should be your travel time. The average temperature is 21°C (70°F), and there’s a bit of scanty rainfall for a few days. October is the start of autumn, and the parks look magnificent with the golden and bronze hues of the falling leaves. The average temperature during this month is 15°C (59°F), and it is undoubtedly the most beautiful month for visiting Austria.
