Does anyone know how far out to sea the seabreeze reaches?
That is; how far out could you reliably kite from the beach without the wind dropping off & leaving you stranded?
Are there factors which change the reach of the seabreeze, or is it pretty much a constant distance?
Cheers; I did see that page, but it only states how far inland the seabreeze can reach.
I know there is a reef break, I think I've heard it said around 1km offshore, from a northern beach here in Perth.
Just curious as to how far out the wind actually comes from.
Of course, only go out as far as you can swim back etc etc.
think about where the wind is coming from and then rethink your question .
Do you think the seabreeze hits land at rottnest and then between rottnest and the mainland is just dissapears ?
ok, re-thinking my question;
Does anyone know how far out to sea the seabreeze reaches?
Still the same question 
Really far.
Or a smidge less.
However its best to kite at edge of ocean due to lack of parking in the middle.
No! it's never enough! 
It's ok if you don't know; perhaps you could post a question on Seabreeze to find out?
Nope, got nothing planned & don't have the experience to have gone, or to go out that far.
It was purely an intellectual question, I'd never considered the question till I took up kiting.
So don't worry guys, I'm not preparing for any stunts that'll get us all banned or anything like that.
Am just curious, and still are.
If anyone does know, please post the answer.
p.s.- mother hens feel free to post your comments too; I love the responses these seemingly simple questions elicit 
A perfectly reasonable question to ask, and no need for snide responses.
I don't know the answer, but the fact that Rotto gets in on good seabreeze action suggests it may be a fair way out.
Hey guys check out the following site. It gives a fairly detailed explanation behind the seabreeze.
www.sail-world.com/USA'Sea-Breezes-and-Why/21958
[EDIT] It mentions - "Typically you will find the breeze extends out 50 to 60 km offshore by mid-afternoon, with the speed increasing from a few knots at the seaward extremity to 15 to 20 kts near the coast."
How about putting your question on the yachting forum they tend to go out a bit further than Rotto.
There are wind maps on BOM that show you the wind strengths offshore it tends to pick up the further from land mass you get as there is'nt disturbance from said land mass.
1 km out isn't that far so if you're asking the question then maybe wait.
I am guessing here but it would have to do with wether it's a seabreeze or a front like if we get a seabreeze in Brisbane(From the north east) it is caused by low pressure and a high temperature which would start closer in than a south easterly that can push up from far down south.
I reckon this calls for an experiment. oceanfire ... we can sponsor you per kilometre that you make it from shore .. all the money raised can go to the navy for your rescue.
not sure of the answer but iv'e kited not much more than a kite line length from shore powered up while mates on the beach struggled to keep kites in the air so haveing witnessed this would like to know where the wind goes ???? was a NE seabreeze
My mate Lucas is a crazy little bastard and he sets his stopwatch and kites 30min out and 30min back. He reckons it actually gets stronger after about 20min. You lose this maniac 'confidence' the first time you ping a line and self rescue a couple of kms through juicy swarms of WA's healthiest jellyfish.
apologies to RPM for the comment made earlier from my profile, left my page wide open to houseguests present and they went a bit overboard lol was not very nice but in their defence they were on the piss....its been a long weekend....in my defnece me being a newb has nothing to do with it. Happy Kiting:0) xx
and actually just noticed that RPM's orginal comment to this post was deleted. seems it gets done in many posts or maybe just dissapears either way explanation in case anyone wants to know in relation to me earlier comment:
he replied to oceanfire saying if he had to ask that question he basically isnt experienced enough to go out that far, i thought as did my mates who commented, that is was a fair question so his reply was actually uncalled for , i do agree my profile comment was a bit too far but well its over now...
Hi Peeps,
I'm not sure but can contribute my experience. I can tell you that the seabreeze starts a lot further than 75 kilometres offshore. Whilst spearfishing 75km west of Dongara, the breeze started to turn as we left, and was blowing by the time we got back (1.5hrs later)

Darn it, I leave work & miss all the action! 
I even got censored
Not sure what I missed, but it sounds like it was a lot of fun.
Was it necessary to censor? I don't take offence at the snide comments, this is the internet after all; it's all fun & games
Thanks for the replies, informative as well as the funny ones.
I'm a fairly analytical person, so I always try to quantify things; I figured the seabreeze would start a long way out, but now I've a much better idea of how far.
Windangoesoff- sounds good mate, you've hit on the formula;
Step one- do something stupid, get into trouble & require rescuing
Step two- get lots of tv news coverage of the search & rescue, later do media interviews about your ordeal & cry on camera, then write a book about the experience
Step three- Profit!!
I'm in!
well ive kited out to the horizon before basicly to the point where you cant see any land kinda scary but yet fun make sure you take a epirb wear a life jacket tell someone where your going but most of all make sure ALL of your gear is up to date and new otherwise enjoy
You forget to add a step - get sponsorship
Seabreezes here on the west coast are a little unique. Depending on a number of factors the seabreeze can extend 80-100 nautical miles (148 - 185km)from the coast.
The huge range is caused by the inland desert but also the warm waters of the Leeuwin current which can actually start it's own thermal breezes.
As to why the breeze can be lighter on the beach than 20m from shore, it's called ramp up. As the wind lifts over the shoreline, it backs the breeze up causing it to "ramp up".
A cabrinha rider would probably explain it better as it mainly happens with taller & wider objects such as trees. On the leeside of a large ramp up (island) you will have a vacuum where the wind will come from 180deg.
Hope that helps the confusion.....
Hey Hiaza,
I think you'll find the phenomenon Oceanfire is talking about is where there is a high pressure south of the state sending winds in a North Easterly direction or offshore. The seabreeze can be pumping SW just 50m offshore and yet still easterly on the beach.
If anyone has been on here long enough (2003) remembers the first Port Beach to Rotto race. We were all sitting baking in the heat on the beach with a gusty easterly blowing. Meanwhile the boats stationed across the channel were reporting in 25knots of Freo Doctor goodness. It came in to within 200m of the beach where it was whitecapping madly and yet we could feel eastery wind on our backs.
Very frustrating as it never reached the beach, but had we been 300m out, we could have been kiting.
The seabreeze goes head to head against the easterly and they cancel each other out. The easterly likely gets pushed up over the doctor as it is warmer and less dense.
That what you mean?
