Ride the wave

To “ride the wave” of something means to enjoy the benefits of a particularly successful, popular, or interesting moment or period of time. The Atlantic, Politico, and others are also “riding this wave” (of the rise in email newsletters). The president was “riding the wave” of good feeling about the economy, but it didn’t last long. He has been “riding the wave” of his girlfriend’s celebrity ever since she was cast in the popular TV series.
