A little less rock ’n’ rollpublished at 15:43 GMT 10 November
Owain is due to catch the ferry from Belfast to Birkenhead tonight and we've heard the crossing can get a little bit choppy. But why is that?
Winds over the Irish Sea can create short, steep waves rather than long, gentle swells, giving the ferry a more frequent, jolting motion. When those waves meet an opposing tidal current, they can become steeper still. With around eight hours at sea, there’s plenty of time to notice this!
It isn’t always rough and today's forecast is currently moderate. Owain will be hoping for a calm crossing after the day he has already endured.
