Highlights include urban knitting and urban gardening, a guided tour through the Kunstmuseum Wien's exhibition, a silly walk contest inspired by Monty Python, dance and karaoke sessions and performances by buskers, and a bike show with Red Bull rider Tom Öhler - the only thing that might be missing is some sunshine.
Deputy mayor Maria Vassilakou said that the aim is to turn the area around the Babenburgerstrasse and the Mariahilfer Strasse into "a giant fairground and living room".
"We want to send a positive message at the beginning of European Mobility Week and also kick of the 'Vienna on Foot' campaign which aims to get everyone in the city walking when possible," she added. Festival organisers are urging people to arrive on foot, by bike, or public transport rather than using their cars.
Things will kick off at 10am and entry to all events is free. For more details go to the streetlife festival website.
