How to View Tidal Heights & Streams

Savvy Navvy makes it easy to check local tidal heights and tidal streams so you can plan your trip with confidence. You can view tidal data in two ways — through the Tides tab in the bottom bar, or by using the Tidal Streams chart detail layer.

You can view tidal data in Savvy Navvy in two different ways, each offering unique insights for trip planning:

• Tides Tab – Best for precise tidal heights and exact high/low water times.
• Tidal Streams Layer – Best for visualising wider tidal flow patterns across your route.

💡 Tip: Combining both methods gives you the most complete picture of tidal conditions, helping you plan safer and more efficient passages.

Method 1 – Using the Tides Tab

1. Open the Tides Tab

Tap Tides in the bottom bar.

• A marker will appear on the chart showing the current tidal direction and speed.
• A purple diamond tidal station marker will also appear. This shows the station used for the tidal heights forecast, along with its name and location.

2. View the Tidal Heights Graph

• The graph displays future tidal conditions for several days ahead (duration depends on your plan).
• Scroll the timeline to see tides at different times.

3. Reading the Graph

Dotted lines and timestamps mark high and low water.

• The tide height can be read directly from the graph.
• The observed time is shown at the top of the graph with a dark blue line and updates as you scroll.
• The current time is marked by a light blue line.
• The background changes to a darker shade at night to show day/night cycles.

Method 2 – Using the Tidal Streams Chart Detail Layer

1. Open the Layers Menu

Tap the layers icon (stacked diamond shapes) on the right-hand side of the chart.

2. Enable Tidal Streams

Toggle on Tidal Streams to view a dynamic tidal flow atlas.

• Arrows show flow direction, with size and boldness representing strength.
• The data updates according to the time you select in the forecast timeline.

3. Explore Future Conditions

Scroll the forecast timeline to see how tidal streams change hour by hour.
