Can anyone explain the stormrider icons?

Hi, folks.
I've been using the Magic Seaweed site/app for a couple of years now for my local break. It's been great for basic tide and wave and wind information. But the "Stormrider" icons they use are a mystery to me. I can sort of make them out, but I can't believe there isn't a legend available anywhere. It's like learning heraldry. What does a circle with one wavy line going diagonally across it mean? What does an arrow pointing to the upper left mean? etc.
These could be useful when I'm checking out other locations if I could just read them.
Thanks to any initiates.
