If you take a look at this map of Sea Surface Temperatures (obtained from marine.rutgers.edu) you'll be able to see some pretty cool things going on. Most obvious are the two different currents that meet off the shores of Hatteras Island- The (purple cold water) Labrador Current, and The (red warm water) Gulf Stream. The Gulf Stream almost always sits tantalizingly close to our shores, but rarely pushes all the way in. The Labrador Current, on the other hand, butts right up against the shore as it pushes down from the North.
Now, take a closer look at Hatteras and Ocracoke Inlet- They stand out as little plumes of (dark blue) cold water (from the purple sound) that jut into the warmer (teal blue) water of the ocean. The wind has been WNW lately, which is evidenced by the shape and orientation of the plumes. I'm not sure if the cold water plumes were completely driven by the wind, the tidal outflow from the sound, or most likely both factors working simultaneously.
Amazingly enough, though, the water along the southern beaches looks like it's over 60 degrees, as long as you don't get too close to the inlets. That's mighty tempting, especially compared to the 45 degree water (or less) found along the east facing beaches.
But the most interesting thing about those plumes of cold water? When comparing their shape and location within the 60 degree water, one will notice that they form the eyes on a teal blue sock puppet. Yay!

There is 5" of ice on the lake I usually sail...if you got open water, suck it up and get out there! :)
That said, your department of homeland security should do something about that sneaky Labrador current from Canada.
Love the blog, keep it up!
I keep hearing reports of ice in the sound. I was contemplating coming down over the weekend. Not if there is ice though. Oddly enough we have not had much ice up here. I'd love to sail in that south shore 60 degree water. However, I'm certain winter is not the best time for taking my first sail in the ocean.
Hahaha, Jake!!
Hey Outdrsmn- I haven't seen any ice in the sound, just on land in the shade. It's been warming up to the mid 30s everyday, and then dipping below freezing only at night and early mornings. That said, the sound water is definitely very VERY cold.

It's pretty flat down there, so it wouldn't be too hectic for your first dip in. Shoot me a note if you're coming down, we'll hit it up!
Other than a fantasitc windsurfing sesh new years day I've been forced to break out the land board. We've had lots and lots of 30 degree WNW so it's been rubber side on the asphalt.
this might be my favorite post. i friggin' love sock puppets!
Good on ya Ralph! Skate sailing is an awesome cold weather alternative to getting wet.
Haha, that's a pretty odd reason to favorite a post Mikey, but I'll take it!
