east coast buoys

Postby purpleandy » Mon Feb 06, 2006 10:03 am

any idea where i can get the height, period and wind data from the east coast buoys in graph form (histogram) to show reeadings over the last couple of days ?? i'ven found it for most of the west coast bouys, and can access the raw data easily enough, but can't find histograms for 62109 and 62026. any hints would be gatefully accepted. cheers !!

Andy, try the NOAA site. It only gives last 24hours though, so the same as what Ben pulls in (except there was no data on the MSW page when I just looked) but you can get your fancy graphs there...

can't find the data for the two i'm looking for on the noaa stuff. must be privately owned - really struggling to find data from them.
62164 and 62166 only appear to show wind and pressure, no height or period data.

next question - anyone know how long would it take an average east coast swell to travel from 62164 and 62026 (if i ever find the data) to the scabs area ??

cheers all

Andy think I read somewhere rule of thumb for speed of waves (in knots) in deep water is 3 x wave period

1 knot = 1.15mph

Therefore, an 8sec swell should move at 8x3x1.15=27.6mph

(Sounds a bit too fast to me, but I suppose it will slow down when getting to shallow water so maybe it is correct :? )

cheers monkey. can anyone confirm this ??? found the data for 62026 (really shoul do some marking :lol: ) its 80 mile off the coast.

*edit* found it. http://www.surfline.com/surfology/surfo ... ecast2.cfm waves move at 3 timesthe period, but the swell only moves at 1.5 times the period, so an 8 sec swell should move at 12 knots.

All this shit's well explained in surf science, even for non-science types like me... I would have thought this'd all be childsplay to you andy :wink:

I prefer "it gets here when it gets here, unless it doesnt, in which case it's gone somewhere else"

Hi there,
I think 62109 (also known as K16) is a historic buoy, so i don't know if there will be any data from it.

you could try looking here for the active buoys http://map.cefasdirect.co.uk/wavenetmapping/advanced.asp
hope this helps

So that is why you are always telling us you think it is going to be 30ft and clean at Cayton Bay every weekend :lol: :lol: :lol:

thought something was amiss when it was reporting 14 ft at 18 secs just off the coast of scabs :lol:

very helpful link - both the buoys i was looking for are historic ones :( ah well - onwards and downwards :wink:

Ah I remember now, thats because an individual wave moves twice as fast as the group it travels in, resulting in the wave at the back (small) moving up to the middle (bigger) getting to the front (small again) then dropping to the back of the group again :shock:

All this making my head hurt, so I will now get back to sacrificing goats whilst repeatedly chanting "Mocka-Hickee" in order to generate some east coast swell for this weekend :lol:

worked out that 62144 is the nearest buoy to scabs that provides height and period. watching it to see when tomorrows swell shows :D

he lies,

he is trying to hack into the buoy to replicate hawaiis swell. therefore ruining MSW forcast and tricking the SW crew into thinking the east coast is constanly sick :shock:

He also hopes it will put off people from going to the coast in future due to it allways being flat when the buoys are reading 14ft at 18secs, therefore reducing crowds.
Are you fucking stupid?

Looks quite close to Scabs that one, Andy. Have you worked out how far offshore it is yet?

cheers ben - i'd found the cefas site, but didn't know that you view the data that easily by the map !!
bought my copy of surf science via the link you posted - will be reading it on my flight to vancouver next week :D
