Hi- When I select an area for extended forecast I see 2 rows that show “feet” for wave.. and I’m not sure how to interpret this. For example- in the pic attached- I see orange row showing “8 ft” then below that 1 foot and then the 7 which I assume is the period. Yet on the chart above I only see one swell with the 1’/7s. What is that 8 ft???

Thanks
