Offshore wind forecast up to twice as strong as on land

 

Hi,

This new video shows how the offshore wind forecast can be up to twice as strong as it is at the shoreline.  Interesting watch for any fisho and the reason why the checking the forecast at the shore/boat ramp is not a good idea and the reason people get caught out sometimes.   You should be checking the wind forecast offshore where you intend on fishing.

 Nearly got caught out last week. Was going to do a quick overnighter to montes as the Dampier forcast was under 10 knots all day. Montes was showing 25 and turned out the guys already over there just sat in the anchorage all day.

Windyty

Tue, 2017-08-22 18:24

windyty allows you to pin point the area you intend to fish and yes it is generally stronger wind out wide than in close.

 Windyty doesn't use BoM

Wed, 2017-08-23 10:21

 Windyty doesn't use BoM data, it uses the GFS model from America (or if you change default the EC model from Europe).  Look in the bottom right corner of screen it will tell you. Both of these perform worse than BoM data (else why would the government fund BoM to exist if they couldn't forecast better than an iverseas agency who offer data free on the internet?)

 Hi Swompa,

Why wouldn't you just use Fish Ranger then?   Fish Ranger uses same data as MetEye and same observations as Seabreeze (Seabreeze just get it from BoM weather stations like anyone else).

So you can go to one site and get the exact same data you get now, on the one page.

MetEye and Fish Ranger use the same data (ie the exact same values) its just an easier way to see the week ahead that navigating to MetEye on a mobile and time stepping through to the right day then drilling down to a point to get a forecast.

 I'm converted to Fishranger too. I use Rottnest for metro offshore but I do know that the live and historic data fro Rottnest is about 3-5 Kn high due to the position of the anemometer especially southerly. The wind funels up the hill and amplifies the reading slightly.

 Fair comments guys.   Fish Ranger would love to sponsor the forum, unfortunatley we are looking down the barrel of shutting down because many people are used to othe sites and reluctant to change, and we don't have enough numbers to get sponsors on board.  We convinced Rapala to advertise on a wether site then when push come to shove they ditched us and started a campain with Willyweather.   Even though Willyweather's users cross the general public probably moreso than fishermen. 

After spending hundreds of $k to get the site built and $2k per month for data and servers, all for not a single dollar back (ok advertising on the site makes about $30c per day), sponsoring other sites is not possible.  Continuing to operate as we are is not sustainable either.

Hi Scottnofish, 

When you go to the Past Weather page you are seeing measurements taken by BoM's network of weather stations that we store indefinately.   The past weather page recalls data from the past week and puts it in a chart.

If you click the little (i) next to the chart title it will tell you which weather station meaured it.   Similarly on the forecast charts if you click the (i) it will give you all the details relevant to it and where the real time was measured.

Fri, 2017-08-25 11:43

I have become a little "gun-shy" when it comes to the weather forecast as every time I think it will be good, it turns out to be crap! Starting to get a complex!

So after checking Sea Breeze, Willy Weather, BOM and Fish Ranger, I have concluded that tomorrow off Mandurah will be a good day to get out.

Would anyone like to confirm my thoughts or shatter my hopes?

Cheers

 Yo Merman.....

 

I'll call you out mate and ask you to inform us as to how you come to the conclusion that "winds" are usually stronger offshore??

 

I think you are giving it a good old squeeze again....

 

I mean its pretty fucking obvious that if the wind is blowing in the East and you travel in a Westerly direction as you move away from the coast the wind be blowing harder in unprotected waters BUT to generalise and state that winds blow stronger offshore is a load of Jizz.....

 

I'll go so far as to say the opposite, and that "winds" are often lighter than what they are compared to inshore waters...

these observations come from experience, unlike yourself I regularly fish 20 plus miles offshore.

Also check sites like windyty and MetEye and you will see the difference between inshore and out wide, oh and timboon both these sites have pictures so even you will understand them.

 Timboon,Wind that blows over

Mon, 2017-09-04 07:23

 Timboon,

Wind that blows over land encounters more friction so the surface wind speeds are (relatively) low.   When wind blows over water the surface friction is less so surface wind speeds are higher.   Have a look at the article: www.fishranger.com.au/the_truth_about_weather_sites

specifically the section titled: 

Why is it Important to Use a Weather Site That Provides Forecasts Over Open Water?

Sun, 2017-09-03 12:58

 Problem with forecasts, is they are forecasts, without an actual wind speed measuring station at the point you are trying to get a forecast for, its just data that is being extrapolated and interpreted from periodically measured data, or from the nearest land station using algorithms etc.

 

Extrapolation is statistically not particularly accurate. Take the readings as predictions not as truth unless there is a live, minute to minute wind speed measurer there.

 Merman,  You do understand

Wed, 2017-09-06 11:27

 Merman,

  You do understand how a seabreeze affects INSHORE waters now dont you?  You being the legend of the deep will surely have noted that often you actually dont encounter a seabreeze when fishing a long way from the land that has created the sea breeze.

 

I feel blessed to have the opportunity to converse with a true legend of the ocean like yourself Merman, Wowee, the regular 20 mile man... Unlike myself lolling around...

 

No you are on the money Merman, i dont ( unfortunately ) fish the legendary 20 mile mark anymore very often, i'm no longer in the commercial fishing industry and in more recent years floating about on Oil Rigs and construction barges miles from land but when i was i was spending half my life out there... I'm actually suprised i didnt see you float on by with some world records hanging out of your chilli bin cuzzi bro.....

 

 

I am greatful to have a true waterman like yourself keeping it real and educating us not so wise folk on here.

 

JGfish i understand the point you are trying to make kinda, sort of.... actually nah i dont...

 

Are you saying the wind has always got some sort of East wind in it? In confusseded....

 

Obviously the wind blows from all directions and sure you can apply the friction theory when the wind has some sort of land that can affect it but to make the call that the wind blows stronger offshore is to be honest a total load of shit....

Thanks JGfish, this was uselful to help get my point across to the old seadog Merman....

What Is A Seabreeze?

Sea Breezes are caused by the uneven heating of sea and land masses by solar radiation. As the sun rises in the sky, temperatures on land get hotter but temperatures over water don’t change much. This causes air to rise over land which sucks in air from over the ocean and creates an air current. This air current forms a cyclic motion that picks up cool air from the ocean and brings it inland to replace the rising hot air. Seabreezes are strongest right on the coast line as this is where the cyclic air currents have maximum flow.

Given the difference in temperatures increases as the day goes on, seabreezes normally pick up in the afternoon and continue into the evening until the temperature on land has cooled.

I'm glad you've learnt something though, it just goes to show you can teach an old seadog new tricks...

 

And FYI, as far as Joe is concerned i'm sure he's a good bloke but just because he's made an app and you now want to tongue his freckle doesn't mean i'll get on all 4's and give you a hand. I'm sure Joe is very knowledgeable HOWEVER, to generalise and state that the winds are often stronger offshore than inshore waters is where i called BULLSHIT....

 

I've proven my point above, anyway I'm off to make an app, no tonguing my freck though you dirty little boy.....

Thu, 2017-09-07 19:49

Hi Timboon,

In the process of creating a weather app, and in the years of research leading up to it, you do learn a thing or two about weather.  I can confidently tell you that wind is definately OFTEN stronger offshore than onshore or at the shoreline and it is due to surface friction. I don't think you actually read the section of article I referenced you to as that explains why.

Don't just take my word on this, here is what maritime safety victoria have to say on the matter.  

transportsafety.vic.gov.au/maritime-safety/recreational-vessel-operators/powerboat/trip-preparation/checking-weather-and-tides

Check out the first sentence:

 Before you go out on the water, always check the weather using a marine weather forecast. Land and general forecasts do not take into account wind speed over water, which is double that over land.

Now they say it is double that on land, it isn't always double but being a safety organisation they err on the side of caution.

We used to have easterly winds of around 20 knots at the mooring at Canal Rocks yet go 4nm offshore and its flat calm, spoke to BoM duty forecasters from off Naturaliste and they said its was same strength at the lighthouse yet we were in glass conditions, this is a regular occurrence down there, Just ask Reece who is fishing that region now and he will back this up

I really hope you have others aiding your judgement because i think you need it...

 

I feel somewhat insulted when you tell me ( us ) as fisherman to check the forecast prior to venturing down next to or on the ocean...

 

I'm on this site for banter but mostly for the opinions and knowledge of alot of the regular posters.....

 

I still cant agree with your opinion that ( Often ) the winds blow stronger offshore than inshore...

 

Its again TBH a misleading comment and not needed here, you can show me as many links as you like but i've well and truely formed my own judgement...

 

Lets also not forget we have members from all over this state/country, you go telling crew from Gerro inshore waters are LESS windy than offshore waters, i think they'll tell you old merman is giving you a good old reach around....

Yeah why fucking not....

 

 

Are you for real?

 

I'm not from Gerro, but most people i know that fish up there dont need to worry about an "Offshore" forecast because to get "Offshore" you still have to bash your way through the 25 knott southerly day in day out for 6 months of the year should you be so idiotic to want to go catch a fish once the seabreeze has kicked in...

 

Of course there are exceptions, if you have the luxury of owning a 50 footer then that might be your thing...

 

What actually is your theory behind why you think the wind often blows stronger offshore?

 

Dont go down that friction fucking route again either you must actually have some science behind your statement ( and no i dont want to read an article )

 

This topic is doing my head in, I'm going to see Frosty down at his bakery on my way to the Fremantle Dr....

Sat, 2017-09-09 07:27

 TB - at high altitutedes the wind speed is the same, its just a large mass of air moving from one spot to another being driven by a difference in air pressure.   If you go several hundred meters up in the air you won't notice a difference in wind speeds on and offshore.   At the surface layer it s a different story, when that wind mass blows over land the surface wind gets trapped in trees, grass, hills, etc and it slows down.  Over ocean the friction is lower and the wind doesn't get trapped so the surface wind blows unimpeded and therefor faster.

Look out the front door, it looks calm on the ocean, the wind is light...go fishing

Look out the front door, dark clouds ocean is full of white caps, wind is blowing very strong and howling... Don't go fishing, go back to bed.

Simple judgement for a simple fisherman.
That's my take on this weather thing.

Sat, 2017-09-09 08:42

 JGfish...

 

Are you suggesting the wind blows in the same direction day in day out?

 

Its funny how some folk get a little stiffy about something and they cant let it go well or go of it i guess...

 

A bit like old Barney, not sure what ever did happen to Barney i think he might be out there still studying.....

 

This friction thing has got you by the nads, let it go mate because its bollocks...

 

If you live in Perth which i assume you do, then anytime the wind blows from ( lets assume the coast runs exactly nth/sth ) 180 deg - 360 deg then your theory is out the window as there is no land that affects it....

 

Say its a 20 knot westerly, are you saying that as you head out to sea the wind increases the further you go? I think not....

 

I dont need to check a forecast to work that out though, anyone with half an idea of how the weather patterns work will have an understanding of highs spinning anti and lows spinning clockwise and how that affects the wind direction as these high/low systems pass us by...

 

This is without even throwing in the arvo seabreezes that will be soon upon us daily...

 

You n Merman should have a bbq down at Herdsman lake, you can watch the "friction" lines all day long and roll around in the grass tickling each other saying we told him so....

 

I'll let you down gently though as i am not here to create enemies, I think i know what you are trying to say you just went about in the wrong way, you have to remember that most of us here are 20 mile legends like Merman and dont need some university jargon....

 

On a finishing note WINDS ARE OFTEN NOT STRONGER OFFSHORE........
