Re: Just general surfing stuff

Am I getting the hang of it..? 200kJ - barely breaking, get out your log = 1 foot 500kJ - surfable, use your twinny = 2 foot 1000kJ - have fun on your small wave board = 3 foot 1500kJ - good overhead surf = 4 foot 2000kJ - really good head and a half, some doubles = 4-6 foot 2500kJ - consistently o...

Re: Just general surfing stuff

nah it's fine, 2000 calories? most of us would walk that off. it is actually the thing that's been troubling me about all this fcuken Kilojoule talk though. What does it mean? Does it mean how much energy passes a certain point in a certain time? Does it mean the energy contained in some portion of...

Re: Just general surfing stuff

No. Around Perth the offshore reef blocks most of the swell but the surf forecasts don't take this into account. I usually just convert the metres on the forecasts to feet, that is if the swell is 3m I'll assume its 3' faces. Because of refraction around the reef gaps even a 3m swell is pretty much...

Re: Just general surfing stuff

Cranked 8470 kj forecast for Lennox head next Monday. any idea what that means? Some set waves with 20' faces. I probably wouldn't go out. If I did I would be nervously and constantly scanning the horizon and paddling for it whenever I saw a distant shadow that might be the one hour set wave on its...

I assume its the same as the error margins for swell height and period as that is what its derived from

Re: Just general surfing stuff

I think thats why I like using kJ, the swell/wave energy with no reference to height. Its then up to me to convert that to wave heights at a particular break if I want to. After about 5 years using it now I usually don't.

Unless I'm talking to someone who doesn't use it.

There is a big problem forecasting for Indo as there are no local buoys that I know of

Re: Just general surfing stuff

I've thinking that to automatically adjust open ocean swell data to wave heights for a given beach/reef you would need to record a series of observations of the actual spot wave heights for that swell height, period and direction. From those observations we could arrive at adjustment factor to conve...

Re: Just general surfing stuff

Steve, do you know what data a wave buoy records and how that data is interpreted/processed/manipulated before being released? Serious question.

Re: Just general surfing stuff

Some uni student did that a few years back. It didn't end well. So people can vote on the truth or falsity of a statement. The majority determines whether it is true or false. People have IDs. Over time you identify who gets it right more often. The votes from these people are ranked and weighted a...

Re: Just general surfing stuff

I've been toying with some concepts involving user engagement with an algorithm to enhance the accuracy of surf forecasts. The same algorithm could quite possibly be tweaked to monitor and measure the truthfulness of internet "facts". If it worked this concept would be worth billions and I would be ...

Re: Just general surfing stuff

Well, its like this, people mistakenly believe its science, but its not. Its just that when enough people truly believe in that swell it will happen - with our thoughts we create the world!
