I. Grey Skies and Sea Foam
Imagine a grey foggy morning at the shore. A gentle tide rolls in, coming closer and closer. The murky water laps at your ankles - a bit menacing, but peaceful at the same time. As the marine layer begins to fade away, you can see into the water to an entire world beneath your toes in the sand.
II. Spring Tide
More popularly known as a "king tide," this is when the tide becomes very high during a full moon.
