April, May, September and October are the best months to rent a campervan and explore Vienna. The weather is better than in the cheaper winter months, and there are fewer crowds and lower prices than in the summer high season. From January to May, cosy up against any bad weather in a coffee shop and enjoy being able to enter museums and restaurants without waiting in line. If you don’t might sharing the city with others, the summer heat between June and August makes the city come alive. Spend sunny afternoons in the parks, at the lake, or touring vineyards, and then enjoy the warm evenings filled with film festivals and outdoor concerts. September and October bring Vienna’s version of Oktoberfest as well as Vienna Design Week. December is the exception to the cheap winter prices when people flock to the city for the outstanding Christmas markets.
