**Kudos to everyone who helped us debug this over the past 3 months.**

Be sure to click on the **Advanced Surf** option to see extra details about the sea-state. Look out for crossing swells and short period local wind swells and chop that will often spoil a groundswell even if the wind is perfect. As yet there is no allowance for this in the swell rating. This is something we are working on.
