Weather forecast sites ?

What do you guys use to check out the forecast ? Ive done a search on here for "weather forecast" but get overwhelmed by the results as we all talk about the weather.

I just need a web site like the Met office for boating, looking at the south / Poole / Solent.

Thanks

Hi Trimix, The unfortunate aspect of weather sites is that the only ones that are any good require you to have a certain knowledge. If you understand grib files these types of sites are the best. Basically these are computer predictions using information of pressure readings from a variety of sources (including live time ships readings). This information has become very accurate in recent years and certainly looking 2/3 days ahead they are very accurate. The most obvious free one to use is Windguru which is essentially a windsurfers site - they give pretty accurate wind / wave conditions worldwide. The ones for Weymouth Poole Lymington and Cowes are pretty good and you can compare the information to the live weather at Hurst Calshot and Chichester. The information they use in all predictors comes from standard sites such a ECMWF and what they call the European Model. There are others but these are recognised as the best. If you have an iPad/ iPhone I also recommend Pocket Grib and Meteo Pro. There are small charges for these. I will make a list of the best UK sites I use and will post these on a second.

I generally find yr.no (the Norwegian weather office) to be pretty reliable. It covers the Channel, at least.

Hi Again

Here are some weather sites I use regularly - do not be put off by any technical aspects. They all have lost of good simple detail. The last one Bramblemet will give you some very recent / live info. I think the best forecast is a comparison between several sites. If they all agree in wind speed and direction you have good info. Feel free to post me if you need any explanations.

WindGURU: United States - Maui (north shore)
BBC Weather - Coast and Sea
Sailing Weather - Marine Weather Forecasts for Sailors and Adventurers - PassageWeather
ECMWF CEPMMT EZMW
sailing great britain wind (gfs) + 0 utc
Surf Reports, Surf Forecasts and Surfing Photos - Magicseaweed.com
BRAMBLEMET - Weather Reports from Bramble Bank

PS on Windguru it takes you to the main USA site. Click on the SPOT MENU on the tabs and you can input an area in most places in the world.

One further simple aspect. Here is an example of a grib file. The little arrows on the chart indicate wind strength and direction. So imagine the icon is an arrow - the "feathers" are therefore at the back of the arrow which is pointing in the way the wind is going. The feathers have two strength readings - half a feather is 5 kts and a full feather is 10 kts. So in wind strength the half a feather is 5 kts, one feather 10 kts, One and a half feathers 15 kts and so on.

Remember this is a prediction only and the further forward you look the info is less reliable. Also the wind strengths are an average only. The wind could fluctuate over and under by 10 kts. You will see windguru has a gust predition as well.

Ah, brilliant. Thanks for that - very helpfull. I shall start looking and get a feel for it.

Of course, the other issue is whats acceptable weather to go Ribbing ? That will be subjective and somewhat dependent on my clothing

*googles dry suits and thermal underwear*

I have windfinder on my phone which gives wind reports on locations you specify, in conjunction with a forecast i find it useful for "on the day" passage planing.

Though with your beast it would be quite extreme conditions before it becomes a worry
