is the average of the highest one-third of the waves. 
The highest waves may rarely be twice the significant wave height.

SYNOPSIS FOR THE COASTAL WATERS FROM BONITA BEACH TO SUWANNEE RIVER-
408 AM EDT Fri Sep 20 2019

.SYNOPSIS...
Interaction between high pressure extending southwest along the 
eastern seaboard and a tropical wave in the Caribbean south of 
Hispaniola is producing a tight pressure gradient resulting in gusty 
east-northeast winds over the gulf coast waters. Buoys in the 
eastern gulf are already reporting winds around 20 knots and seas 
around 5-7 feet. This has warranted the issuance of a Small Craft 
Advisory for the gulf coast waters through Sunday morning. Winds 
will decrease to around 10-15 knots on Sunday and continuing 
through next week as high pressure shifts south allowing for the 
gradient to slacken. No other marine impacts are expected through 
the period.
