Ocean Conditions

“Oh the waves crash in and the tide pulls out,
It’s an angry sea but there is no doubt,
That the lighthouse will keep shining out.
To warn the lonely sailor”
Ready for the Storm, Kathy Mattea

The status of the ocean on a day-to-day basis is of critical importance to much of the ocean community, whether they are lone sailors out on the sea, researchers studying the ocean, people playing in the ocean or workers doing business on the ocean.  Whether its big surf, water temperature changes, incoming weather, or just knowing the tides, an understanding of ocean conditions is critical. Many sources are available across the planet. The collection below is just a start in providing access to basic information about ocean conditions.
