article: Internet users were left scratching their heads after an old hoax video showing a wave rider surfing in front of the Sydney's Opera House started trending for a second time. The video was uploaded to Twitter on Tuesday morning by popular Sydney radio duo Fitzy and Wippa, before quickly being reposted by a spell of other sources. The posting of the video comes in the wake of heavy storms which battered Sydney overnight, with parts of the city experiencing the heaviest rainfall in 100 years. A hoax video showing a wave rider surfing in front of the Sydney's Opera House has gone viral for the second time . Some users have referenced the weather as the trigger of the strange phenomenon, with musician Fortafy uploading the video with the following caption: 'storm brings out surfers in Sydney Harbour.' The video was originally posted by Sydneysider Darren Johnson following strong storms and tandem heavy swells in June 2012. YouTube commenters were quick to point out inaccuracies in the video, such as the appearance of rocks around the Opera House and the cardboard-esque appearance of the man in the final shot. It was also rebutted by several wave experts who vowed it was a sham. Ben Macartney, a swell forecaster, told News.com 'the only way you'd get waves in there would be a giant tsunami coming out of the Pacific.' 'Even the most powerful ocean waves known to man, I think, would still really struggle to make it up there.' 'Theoretically it's impossible for ocean swells to really break that far inside the Harbour. In other words, it's not really possible.'
