This is an unofficial forecast. The aim is to help people with their forward planning. Current wave height calculations don’t take into account the different fetches for different wind directions, nor does it take into account the duration of the wind.
Always check with CalMac for the details of the service between Brodick and Ardrossan, or Lochranza and Claonaig / Tarbert.
