Marine Weather

If in doubt, don't go out!

New Zealand's weather can be highly unpredictable. Enjoying the sunshine and a light breeze at home is one thing, but the wind can be twice as strong out on the water. We've got you sorted with a range of services to keep you on top of what the weather is doing. 

You can get the latest on your local marine weather situation via:

 A few handy weather tips:

  • Marine forecasts tell you what the weather is expected to do, but there's no guarantee. Keep an eye out for any changes of clouds, wind direction & strength.
  • Tides are important, as when there's wind against the tide, you know to expect a rough sea state (especially in boats under 6m in length)
  • Looking to cross a harbour or river bar? Never cross without the required experience and local knowledge. Check out our 'Raising the Bar' seminars for information to keep you safe.
