Still Clip Showing Wind Direction

This is a great tool  You can select to see the wind, waves or swells and predictions for future dates.

The still clip above shows the wind.  You can see it streaming down from the northeast over the southern states and North Florida.  The center of a low pressure zone is sitting just north of Canevaral.  At the time shown,we were getting south/southwest winds.

You can see a lot of areas.  If you were traveling, you could tell where you would have a good chance of finding good detecting conditions.

The tool also allows you to look at the swells and waves.  It is a great beach forecasting tool that I'll be using a lot.

You can see a center of circulation just north of Canaveral.  In this clip they're getting northeast winds.  We're getting a west wind in the same clip.

To see this in motion, along with a lot of other neat and useful stuff, use the following link.

I'll add this to my Surf Conditions  and Waves link list as soon as I get around to it.

GoldNugget sent me the link.  Thanks!

Here is an illustration I showed yesterday.  I'll start with it so I have it to compare with the next illustration.


One thing is different in the illustration below.  It shows a cut instead of a gently sloping beach.  When there is a cut, as shown in the following illustration, the water bangs against the front of the cliff when it gets up that far.  That means that the surge can hit with a good amount of force, and instead of the water gently slowing and dropping off sand and other objects, the you get a more forceful backwash.
This illustration assumes the water hitting the beach straight on rather than at an angle.  One other thing that occurs in this situation is that the surge continually hits the backwash and they pretty much cancel out each other.

The point where the surge and backwash collide will often stop the flow enough to drop out any objects at the point of the collision.

Of course for any coins to be caught up in either the surge or backwash they must be exposed rather than protected by the sand.  That can be either down near the breakers, when they are carried up the slope, or on the slope.  They can also get carried either up or down, depending upon the force of the surge and backwash.

As the tide goes up, they tend to collide higher on the beach, and as the tide goes down, they tend to collide lower on the beach.

In this scenario there is not a lot of sustained momentum as there would be when the waves hit at an angle and slice away at the beach.

Dan B. found a sea glass blog site that has a post on red sea glass.  It shows a neat distress lamp with a red lens that was found near a shipwreck site.  It also talks about other sources of red sea glass. Thanks to Dan B, for sending me the link.

This morning the surf was up a bit on the Treasure Coast.  The water got up a little higher than usual.  While the waves weren't bit, they were nicely formed and big enough for a lot of surfers to be out.

I also saw a good number of detectorists out early this morning.

I suspect that in places where the beach is angled just right that you might be able to find a few modest cuts.

Happy hunting,
