Weather updates

If you are worried about the weather, then don't be. If the sea looks a bit uncomfortable then you can simply change your sailing to another time or day!

Interislander Aratere in the mist 1000x600Do I have to sail in bad weather?

Typically, strong winds and gales from the north are nothing to worry about will simply make the beautiful scenery a bit more dramatic.  The water will remain calm, but our outdoor decks might be closed.

However, a strong wind from the south, known as a Southerly, can cause significant swells.  Interislander ferries have stabilisers so we will sail in choppy water which can be a little uncomfortable for some.  There are also times when we delay or cancel sailings when it’s too unsafe to go.  In these circumstances, we’ll try and get in touch with you.  Find out more about receiving notifications when there are disruptions or cancellations. 

We don’t all have sea legs so the decision to sail on the day lies with you. We just need to know an hour before the scheduled departure if you want to defer to a later sailing.

To get a forecast for the sea conditions, visit swell map and look at the ‘swell height’ map.   This gives you expected wave height in a colour code with anything upwards of 3 metres considered uncomfortable in orange and red.  Fairer weather is colour coded in green and yellow. 

Can I change my sailing because of the weather?

If you want to delay and go on a sunny day, that’s fine!  You can change your sailing free of charge to one of equal or less value.  If you want to move to a more expensive sailing, you can simply pay the difference with no penalties or surcharges.  

To change your sailing, please call us on 0800 802 802 any day from 8am to 6pm (5pm on public holidays) or drop us an email at
