Where can I see wave energy?

The table layout has a new column. See it highlighted in red, below.

Seeing a kilojoule (kJ) readout for each timestamp might be all the info you need.

But we recommend using the toggle in the top right of your forecast page to switch to our graphical forecast layout. It'll help you make sense of changes in energy from timestamp to timestamp.

Using the Swell and Wave Energy graphs

Note: these advanced graphs are collapsible, so check the ^ symbols on the left-hand side of the page to open them if hidden.

You can now change the Y-axis of the swell graph using the Order by Energy toggle.

• Hover your mouse over individual swells to understand the relationship between height & period. The height and period of a wave determine the energy it carries.
• Use the Wave Energy graph below for the sum value of energy in the water. The overall energy value is calculated as the sum of the energy of the individual partitions and those are calculated taking into account the impact on a given spot.

At neighboring spots sharing similar/identical swell data, energy readouts at exposed spots will be higher than sheltered spots because they are more exposed to that same swell.
