How to use Waves in Savvy Navvy


Wave heights, periods and directional data availability varies based on your Savvy Navvy plan. Learn more about Savvy Plan Pricing here.


Savvy Navvy makes it easy to check wave conditions so you can plan a comfortable trip with confidence. You can view wave data in two ways: through the Waves tab in the bottom bar, or by using the Waves chart detail layer.



Quick answer


  1. Tap Waves in the bottom menu, then tap anywhere on the chart to see wave height, period, and direction.
  2. You can also turn on the Waves layer to see wave conditions directly on the chart.



What Waves shows


The Waves feature helps you understand how the sea will feel, not just what the weather is doing.


You’ll see:


  • Wave height (m or ft): how big the waves are
  • Wave period (s): time between waves
  • Wave direction: where the waves are coming from


Example:

1.3 m / 6 s means waves are 1.3 metres high with 6 seconds between them.


How to view wave conditions


Method 1 - Turn on the Waves layer

This gives you a quick overview of how conditions vary across a wider area.



  1. Tap the layers icon on the right side of the screen
  2. Under Chart details, select Waves
  3. View wave conditions visualised across the chart


How to understand the conditions


Savvy Navvy translates wave data into simple comfort levels to help you decide quickly.


  • 🔵 Calm: smooth conditions
  • 🟡 Moderate: some movement, generally comfortable
  • 🔴 Rough: more challenging conditions


Method 2 - Tap the chart

For detailed information on heights, periods and direction of waves.
