Ok all you ocean beach hunting experts...

From a physics standpoint, what exactly happens during the late fall/winter that causes sand to be pulled off the shores?

I understand there are NE'str storms that bring winds from a much different direction than generally occurs during the summer, but is that the primary reason for the differencs? Is there something to do with changes in rip tides and other currents that help drag the sand out with the high and low tides?

Just trying to expand my knowledge and understand sand movement a bit better.
 
in a pretty basic enough way that even I can understand it! It still seems like there should be a better way of predicting which storms in the fall/winter will pull sand off the beach and which ones end up depositing sand back up there again.

Oh well - I have a feeling the answer is really just to learn from experience - get out there as often as possible, take pictures, make notes on weather etc...

The information at the website above is very good. There are many variables involved. There is a lot you can learn and many books have been written about beach erosion. Even after reading as much information as you can find there is still nothing better than firsthand knowledge gained by observation. Just as important as wave direction and something many people don't pay attention to is wave period. Small waves with short 2-3 second intervals can erode a beach faster than a big storm with large waves where the wave period can be as high at 15 seconds. The reason is that with a long period between waves the sand that has been picked up by the waves has time to settle back down between waves so it actually erodes slower. Waves with short intervals don't give the sand a chance to settle back down and continue to pull it out as it it were on a conveyor belt. A good way to keep track of this is with the Surf Reports. Surfers websites have great wave information that we can use as well to help predict when the beaches will be eroding or filling back in. Here is a link to Wave information. Note that it gives wave heights, wave direction, and wave intervals. Hope this helps!

I've read alot of the GoldenOlde information, and although there is a ton of valuable information (especially since I'm using a CZ20), I haven't found as much as I had hoped regarding beach erosion.

I really like the info. on the 2nd link you provided and I'm sure I'll use that alot!

Your point about the wave period is the kind of info. I'm really looking for!! After you mentioned it and described the way it works, it seems like it should have been common sense, but I hadn't really seen anything presented the way you quickly described it - thanks very much!!

As you said, more than anything it's just going to take me time and experience to learn more, but I really do appreciate the comments you made!
 
it's a crap shoot check as many spots as you can during and after a storm hope you picked the right one...but your sure to hear that a guy a 1/4 mile down the beach got a $20.00 gold piece!!! so ya keep chasing those storms!! who knows??:shrug::confused:or:super::thumbup:
 
over time as you get to know your beaches you will learn which wind directions cause the most erosion and youwill develop landmarks which will allow you to judge how much sand has been removed or filled back in. It takes time but it's worth the effort and in the process you will develop a who new appreciation of the Ocean. Winter Beach Hunting is a totally different type of hunting than Summer Beach Hunting. Winter Hunting is a combination of knowing your beaches and luck. Summer Beach Hunting all you need to do is concentrate your searches in front of the Lifeguard Stands and you can't help but get lucky. In the Winter targets are spread all over the beach. Good Luck and Have Fun!!!!
