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?

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;

Still the same question

Depends on the wind
Hope that helps

Still the same question

it comes from further out than you will ever reach . that good enough ?

Don't know, but sure sounds like you have something in mind...

I would suggest not far enough for you to get to NZ or Tasmania, at least not on a seabreeze.

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.

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 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.

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

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)

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

i guess it goes up then

You forget to add a step - get sponsorship

Only because your reply was out of context after the one you responded to was nuked for being, well, not quite in the spirit of sharing the stoke.

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?
