Wave height on Seabreeze charts

Hi everybody,

Long time user, first time poster. I'm a keen kayak fisho who loves using this site, especially in Winter when I'm not yak fishing, but rockfishing. I find Seabreeze invaluable to know when to go or not go!

Enough about me. I have noticed something in more recent times on Seabreeze that has been annoying the hell out of me. I use the Wave Height & Wave Direction charts and have noticed a discrepancy between the Wave Height on the Wind & Wave Forecast chart (in metres) and the chart below, the Wave Direction chart which has the Wave Height in feet. For any given time, I've been finding the Wave Height in feet is not the equivalent in metres.

Am I missing something very basic here?? I've written to the Seabreeze Admin/Moderators, or at least thought I did, but never got an answer out of them. Can anyone help please?

Thanks!

Seabreeze for wind, coastalwatch/swellnet for waves.

Are you the same guy who wrote in at 3pm on Friday? Sorry .. we need to have a weekend from email sometimes, and your enquiry was answered today.

Can you be more specific? i.e. Which location, and what's not converting to what, on which day?

Thanks for your reply Laurie. No, it wasn't me - it was at least a couple of weeks ago that I wrote.

Location: Sydney
When: Everyday
Link: www.seabreeze.com.au/graphs/nsw.asp

Take the forecast for Sunday @ 1pm - the top graph (Wind & Wave Forecast) says wave height 0.5m while the graph below (Wave Direction & Period) says wave height 2'10". 2ft 10inches is NOT 0.5m. 2'10" = 0.86m

Like I said, it might be me missing something about the 2 charts. Eg. "wave height" means something different on the 2 charts??

Thanks for helping.

Guys it's free info,..... Don't you remember local knowledge,,,,, the real surf check where you jump in your car etc etc... Tides. Moons, banks moving beach erosion. I like it when every computer is wrong I get uncrowned waves. For every time I drive north it's only every other I score if I'm lucky. Suck it up deal with it, learn to read a synoptic chart, learn to read a sea chart , buy a boat, jet ski? Buy a fish learn to sup, if it was easy it would come in a cereal box, sometimes the greatest gift is the journey and not the destination... Ahhh we'll rant over

Swellnet is telling you the predicted wave heigh, the rotto buoy is telling you the swell amplitude.

Ok might elaborate on my statement.

Seabreeze is by far the best site for wind prediction updates and current strength.

But the surf sites are much better at telling you what conditions will actually be like at different beaches, that said their wind forecasting is average. Also they tell you in words what is the swell/waves are doing which can be a lot more informative than a graph. I think the seabreeze graph my be better if your off shore in a boat, but if your after surf condition look elsewhere.

A combination of sites gives you a good guide on where to start looking for a surf or sail.

But local knowledge and searching is a key, some of the best times haven't been predicted, as razz has correctly stated.
