    It's a snapshot. Just like a picture of a guy boosting a big air. Then he eats it. All you see is the big air. Same with a buoy reading. Try looking at it again a few times to see if there is any consistency in direction, size etc. It takes intelligence to see patterns in what uninformed others (shark c-hunter) see as random bits of info. Or try investing in a Magic Eight Ball: "Ask again later".

    Of course buoys are useful in inputting data for forecast models. That's a far cry from thinking the buoy will never fail and just because you see 3 feet at 8 seconds 100 miles offshore that's that what will be at the beach when you get there.
    im not a buoy expert,but I know they usually give 2 readings that are miles apart,like itll say 2ft at 11 seconds,then 12ft at 15 seconds,i don't know why,maybe that's the far offshore buoy idk.I do my predicting from the weather channel.just watch for the low pressure,hopefully theres a high pressure to the west so it pushes it offshore,and watch the isobars and the closer they are together,the better the swell.if the isobars are far apart,that usually means onshore victory at sea,while whoever is near the close together isobars will see epic surf.

    I don't ever check surfcams anymore.i think they should destroy every single one,because its a big let down.u watch onscreen and its like eh,il stay home doesn't look that good,and the next day everyones talking about how epic it was,or its too big but u find out it was perfect size.the best way is to just go down to the beach and check the surf,for those of us who are fortunate to live near the water

    cep you may not remember lunchtime so I won't expect you to remember explaining all this to me when I first came on the forum. Pressure readings have been my biggest factor in planning sessions. There are of course several elements at work though you said look for the low and that's what I do. Especially with big changes in temp on the forecast, I know then too that at least something good is coming. Keep it simple and yes, go check the break. I've scored when not expecting to from just checking the break for the hell of it. I've also lost out (not often) when not checking the break even though it would've been well worth the effort.

    I haven't had any luck with the "spot on" feature and this classifies under accuracy. I'm just trying to help so don't freak on me. Maybe someone else can work it in with the "spot on" thingy.

    Today @ 3pm SI calls for 6.7@7 ESE, for my zone.
    The 44066 is currently reporting 9.5@12.9 E (2pm)

    That's all, thank you, good day.

    It's 75 miles off the coast. The SI forecast is not for 75 miles off the coast.
    You guys still haven't figured this out eh?
    Look at this image. (now obviously wave significant wave height/swells are different. I understand that. But this gives a good idea.
    WaveHeight1_northeast.jpg

    Another example from hurrricane Bill of swells eroding
    sandy_hs.jpg
    Notice how wave height is decreasing as it gets farther from it's source of generation and closer to the coast? Swells erode. Even ultra powerful ones. 75-100 miles off coast is a totally different place. That's why nantucket island on an average 8-10 second period chest high south wind swell will have bigger wave heights than ri. It's closer to the source.
    THAT'S WHY A BUOY THAT SITS ON 75-100 MILES OFF THE COAST CAN BE REPORTING DIFFERENT WAVE HEIGHTS THAN WHAT IS HITTING THE SHORE!!
    Wow.....

    Oh and it should be added steep waves(the stuff we get 90% of the time) decay rapidly over distance compared to a groundswell like bill.

    Can't you use the Montauk Buoy for RI? I believe it gives a near shore (>25 miles ) and offshore (<25 miles) forecast from Maine to NY.
    I find it accurate for NY. Not sure if it is North of NY.
