2012-02-14 01:18:08 - How to get long range forecasts from NCEP
Go to: http://www.emc.ncep.noaa.gov/
Select: GFS logo
Under U.S.-No America select: "View more model forcasts"
This takes you to "Model Analyses and Guidance" page.
Select: "Model Guidance"
Select an area (for SOL WR leg 4 select "Asia"
Select a Model Type (start with "GFS")
This will load page with "Available Model Cycles"
For surface winds select "10m_wind_precip"
That will load a box of colums with projected winds from 3 hours out to 384 hours out. Select any and a chart of the projected Wx for that day and hour will load. This can be saved as a gif file. From the chart page you can return to the Available Model Cycles page to select another time in the furture.

Very helpful - thanks Jack...

Be interested to look at some of the other models implied in your post - they can often be helpful when trying to predict how later winds will change from the current forecast
I help develop the client interface for the best online ocean racing sim there is... __/)/)_/)__

Are these published earlier than NOAA's grib file runs?

Saildocs is also a good way of getting long range forecast.

If you send the following to queryATsaildocs.com...
Subject: anything you want
Body: send GFS:40N,61S,40E,140W|1,1|0,6..336|PRMSL,WIND

... you get the grib file for the specified area and timeframe in return.

You can also subscribe...
Subject: anything
Body: sub GFS:40N,61S,40E,140W|1,1|0,6..384|PRMSL,WIND days=0 time=23:00 interval=6

... and you get this sent to you 5 min after each time interval starting from 23z tonight. (Saildocs runs subscriptions 5 min after every 1/2 hour and the full 384h run is normally finished by then).

Red Eye - Key Lime Pie-gatta 2025

Opposite the Bahamas at the tip of the Florida peninsula, we find the Florida Keys, a honky-tonk arpeggio of islands, where another SOL classic, the Key Lime Pie-gatta, so-called after the famous local condensed-milk-based tart speciality, awaits to be navigated once again. We’ll race its “Red Eye” 180nm in very-American Santa Cruz 52s, ignoring such artefacts as bridges, causeways and piers joining the keys one to the other and to the mainland!

Sail Around Turkey 2025


Welcome to the 11th running of one of Sailonline's most iconic races, where our fleet races the length of the Turkish coastline from Hopa (the easternmost harbour on Turkey’s Black Sea coast) to Iskenderun (the easternmost harbour on Turkey’s Mediterranean coast). It’s a 1,372nm race and aboard our classic, 1st decade of the 21st Century, version 2 IMOCA 60, you should be able to get around the course in less than a week. That is if, of course, once you get out of the Black Sea you don’t stop to enjoy the sights or a BBQ or two in the Golden Horn, or on the Marble Islands, now land-locked Troy or Gallipoli or any of the myriad Aegean islands, that you shall have to carefully navigate past.
