Ever wonder what causes upwellings and the need for boots on hot summer day? Well wonder no more - Jon Coen has a great article up on GrindTV right now - here's an excerpt:

"Explained most simply, itís when cold water from deep in the ocean rises to the surface. The sun warms the water on the oceanís surface; as it penetrates, its heating effects lessen. Therefore, water farther down the water column is cooler.

Pretty basic. It makes sense that if that water were to rise up, it would make your lips blue and toes tingle.

But what causes the upwelling of deep, colder water replacing warm water along the coast? Thatís a little tougher. Thereís almost always wind blowing across the oceanís surface. Which ones cause that warm water to move?

Thereís a phenomenon called the Coriolis effect, which causes surface water to move not always in the direction of the wind, but at a right angle."

Ice cream headaches in South Jersey this weekend. Baking hot with only surfers with wetsuits in the ocean.

Midday on Sunday I tried to trunk it with a top. Feet were numb in 20mins.
