Well don't look at the weather on the Freeserve homepage. Just tried to get a local forecast. It gave me the 3 day forecast from thursday and it got that wrong!

It may be a plug, but you can get the best of the weather websites from my own weather website.

For general forecasts, I've found Theyr to be excellent though only accurate up to 18 hours ahead !!! Otherwise, Metcheck are very good.

For marine, the inshore waters from the Met.Office is good and for long range 7 day wind forecasts, the GRIB data from Saildocs is excellent. You can download the Raymarine software free and use it as a GRIB data viewer. Around Ireland, Met.Eireann has very good marine forecasts too.

Hope this helps

Have you tried the dear old Met office. You can get accurate 3 to 5 day forcasts which you can print out. The print out shows a synoptic chart plus wind speed (F4 etc) plus visibility plus seas state for each day. Only trouble is you have to pay i.e. 3 day forcast is 2 tickets @ 50p each. Still not bad.

You have to register with username & password then deposit say £20 via yer credit card then hey presto. Actually I am using it over hear for 5 day forcast Gib to Malaga.

I like this site for long range forecasts.

You can view different computer models in one place. If there's a big difference I take the view that no one knows, but if they all say similar they're normally correct.

When the forecast says " A complex weather system" this actually means they don't have a clue about what the weather will be like.

For 5 day forecasts, try these Bracknell synoptics on the Swiss Westwind site.

.

Those are exactly the ones that I have on my weather website too though I have to say that Theyr do change their forecast alot and anything over 18hours is genereally not time accurate.

The synoptics are hard to beat for long range. I'll be adding GFS synoptics to my website as well soon.

This is about which sites really are accurate at weather prediction, not promotion of links

Which weather sites are the best at 'forecasting' weather? 6 hours is easy, which ones give reasonably accurate 5 day forecasts

Generally speaking, web links are what you are going to get if you ask for lniks to accurate forecast sites, but if you read all of my posts, I do say which is the most accurate. I suppose it depends what way you want to read into each message. OK, I maybe be promoting links, but only the fact that the other forum members mentioned exactly the same sites and that I concur with their analysis of accuracy.

From last Friday, through the Saildocs GRIB data, I could see the development of the current low pressure system to the northwest of Scotland and it predicted accurately that there would be gale force winds in Malin and Hebrides. So that seems to be 5 day accurate forecasts... There is an online version of the GFS predictions but I have not got them on my own website as of yet. The free GRIB data which is e-mailed to me daily is only 15Kb and Raytech Navigator (you can use the free demo) are the best and most efficient way of wind forecasting. Online, you get large 150Kb images to download but they aren't animated like the GRIB data can be.

Here is a promotional link again but I am only promoting it because it is an accurate 5 day forecast (why else would I mention it?) My motives are purely clean and proper - I'm not worried about hits to my own website but rather that you judge it by it's usefulness.

If you find these links useful, I will put them on my own website and then it will be useful for everyone. I'm here to help.

I have to say thate Wetterzentrale does it every time. You need to understand what you are looking for .. the Sembach faxes are great - simple to understand with fronts (I can never work out where to draw them) and precipitation marked up.

For wind and wave the US navy charts give good medium term forecasts of wind direction and strength, together with significant wave height. They also have a very good humidity forecast that is helpful when fog is a possibility.

Personally I dont bother much with the aviation charts - they are more normally concerned with weather at altitude which doesnt fuss me.

The only real downside is the requirement to thumb through the german prompts - but the met terms are often understandable.

As Mark says, synoptics are the best way of working out a 5 day forecast but you have to bear in mind that in our latitudes depressions and their associated fronts can speed up, slow down, veer off slightly and develop new little depressions, which is why theyr.net will change their forecasts accordingly as information is updated.

But basically, Bracknell's synoptics seem to be the best. ECMWF 5 day charts give a rough indication as well.

What I was trying to achieve, was to find the most accurate weather sites.

This one has been bookmarked for quite some time, but doesn't reallly register in the accuracy stakes

See <A target="_blank" HREF=http://www.ybw.com/cgi-bin/forums/showflat.pl?Cat=&Board=ym&Number=365816&page=0&view=expanded&sb=5&o=7#Post365816>http://www.ybw.com/cgi-bin/forums/showflat.pl?Cat=&Board=ym&Number=365816&page=0&view=expanded&sb=5&o=7#Post365816</A>

That pretty much summarises my opinion of the site.
