Flying is very expensive. The crossing time is twelve hours and fourteen if it goes into Orkney. It’s always a lottery how the seas are but it’s guaranteed to be rough in January. Sometimes in June you just can’t feel a thing. Very pleasant. So in other words choose to go in the summer.
Why do they have to sensationalize weather these days' giving them names to make them sound more dangerous or as one newsreader said " we're getting a weather BOMB" . Back in my day it was " its pi###ng darn and that winds gerrin up"' we turning into southern softies.
