What 's particularly impressive about the performance is that the film 's debut telecast -- despite generating massive buzz on Twitter , clocking a whirlwind 5,000 tweets per minute during its peak -- initially delivered a somewhat disappointing 1.4 million viewers a few weeks ago . Viewership has increased to 2.1 million viewers after the first episode . It 's now the most - watched premiere for an original movie in Syfy history . The final ` ` Sharknado '' airing will be on August 22 ahead of ` ` Ghost Shark ''
