I see you didn't take PCS advice metic. Strange, cause sometimes your posts sound like him and he posts good advice written in nice short sentences like you sometime.

Interesting you keep posting lots of shiny maps that show a high over the state on the right and a storm weather system developing around 42 degrees south (Could be half way to Antarctica) on the left on the weekend before JC disappeared. Somehow I keep thinking of Dory in the movie Nemo "Look shiny thing, look shiny thing".
Are you still insisting there was a storm on the weekend before JC went missing? The Sunday Times front page 19th June 1988 has the photo of detectives outside in shirtsleeves (on 18th June) looking at the backyard of the murder house. The West Australian has the weather forecasts (around a page each day).
Friday 17[SUP]th[/SUP] June 1988
: Temp 16.1 at 10.10 pm and 21.5 at 11.30am
Saturday 18[SUP]th[/SUP] June 1988: Morning showers. Outlook fine. Temp 14 20. West to SW winds 15knots easing to 10 knots by late morning. Seas 1 m on a swell to 2.5 m.
Sunday 19[SUP]th[/SUP] June 1988: Temp min 13.6 at 8.50 pm and max 20.6 at 11.45 am.
Monday 20th June 1988: SW winds at 10 to 15 knots easing to 10 knots by late morning. Seas should be 1 m on a swell of 3 m.Temp 10.7 degrees at 7.30 am and max 18.4 degrees at 2.25pm. The coldest overnight temp was 10.7 degrees at 7.30am, This is accurate reported on Tuesday 21st June, for what its worth.
The seas 1 m and swell of 3 m with winds SW are general boating Perth City Coast forecasts but with the SW direction Cottesloe is sheltered by the groyne and Rottnest. Ive posted what similar wind and swell conditions look like on Cott beach in June this year.
Source live webcam Cottesloe beach Saturday June 3 9.00am.
Perth City Coast forecast is 2.5 m WSW winds for Sat 3rd June 2017 8.00am. That is real like example of what a Perth City Coast forecast of 2.5 m swell in a WSW direction looks like at Cottesloe beach.
Theres always been stories of huge waves and there always will be .
Its one of those topics that can be over exaggerated and easily misunderstood .
Mixing "forecasts" into the conversation is foolish .
"forecasts" arent the Real Thing .
Real statistics are all that matter at the end of the day .
A swell buoy is the best thing to get information about swells and periods.
That is the language i am using here ,when talking about swells , periods etc .
Real metres as measured by a buoy .
No estimates... just a simple language that people use because its most accurate .
The Australian govt uses them all around the coast and so do most govts around the world .
http://www.transport.wa.gov.au/imarine/tide-and-wave-data-current.asp
Theres plenty available to the public,
ive used the wa buoys for near 20 years . Lots of people use them everyday ,
if theyre on the ocean, because it measures.
Then you can become very familiar with it day in day out..
Theyre very good ,easy to understand...
They're usually accessed online and often near "real time" or delayed a few hrs at worst .
Big wave Surfers use them specifically to help them pursue riding huge waves .
These examples are to show some examples of actual 5m or more swells on WAs coast and the seriousness of a 5 ,6 or 7 metre reading .
As is shown on my graph with the 6/7m
Spikes on 17th &19th june . 6 & 7 metres , this equates to imo 2-3 metres at cottesloe in this particular event . Analysis of this particular swell event with the information available to me, thanks to the p.oceanographer.
The coastal waters forecasts completely supported that height of 3m , ive tried not to overexaggerate throughout so im going out on a limb to call 3m for cottesloe.
The direction of the incoming swell is appropriate to arrive unhindered (by rottnest) quote Physical oceanographer:
On the swell direction :
"around *287.5, degrees
then jumps/spikes to *319
and *343 degrees or so ."
Rottnest island doesn't create a major swell shadow on Cottesloe beach during west-north-west swell events "
All this evidence points to big waves (for metro beaches)
3 metres for cott is extremely rare .
my guess is this is rare,
not-even-once-a-year type occurence !

"A STORM front will bring swells as high as eight metres, creating dangerous conditions for fishing or surfing in Perth and the South West this weekend."
