For years I've been using GribUS for weather, but now I've gone over o the dark side and got myself a Mac. It seems GribUS don't support the Mac. Any recommendations gratefully received.

+1 for Zygrib. It's what I've been using the last couple of years.

I've downloaded Zygrib - still trying to come to grips with it. How does it compare to USGrib?

More up-to-date, comprehensive and stable. A light-year ahead of USGrib and should work better with a Unix-based OS like MacX.
I've use it on Win XP, Win7, Linux and even on Snow Leopard.

I use MeteoEarth from the App store - absolutely stunning app that uses ECMWF gribs.

Sorry, don't like it at all. All I get is colours. If I can't figure out how it works in three minutes flat, it's no good for me. Also, the fact that you have to take out a subscription for any forecast beyond a couple of days isn't flagged up when you make the initial purpose.

PocketGrib also works well on my mk1 iPad. And WeatherTrack is a quick link to lots weather websites.

Back to the original query. Yes, zyGrib has Linux and MacOSX versions. Meteorologically, it is no better and no worse than any other GRIB service. I think that it has more options than any other GRIB service or App that I know about.
Virtually all GRIB services use the NOAA GFS. None is any more accurate than any other. Windguru (free version) is simply an interpolation from the GFS grid points that are 0.5 degree lat/lon apart.
There is a list of GRIB services at http://weather.mailasail.com/Franks-Weather/Grib-And-Objective-Forecasts-Reviewed.
And Apps at http://weather.mailasail.com/Franks-Weather/Grib-Files-Apps.
Any additions, please?
Ric. How do you know that Meteoearth is ECMWF data? As far as I know, it is the NOAA GFS. It looks very like http://earth.nullschool.net/#current/wind/isobaric/1000hPa/orthographic=314.27,7.50,408. But, whatever, thank you for pointing me at this App. It looks a useful demo tool although of little practical use when sailing.

Since my original post I've been trying out the ZyGrib. Mostly I'm happy with it. It's more sophisticated than the old UGrib and therefore takes a bit more getting used too. That said I'll persevere, these things tend to improve with familiarity. Thanks for all responses.

I have downloaded the MeteoEarth App, from https://itunes.apple.com/gb/app/meteoearth-for-ipad/id586878855?mt=8. There are versions for other platforms. You get a 36 hour forecast. If you want forecasts out to 5 days, you pay a small fee of £1.49 for 3 months and £3.99 for 12 months.
I have checked with MeteoGroup and, as Ric rightly said, it is using ECMWF output. It is a better presentation and easier to us (to me, at least) than the Earth Wind Map at http://earth.nullschool.net/#current/wind/isobaric/1000hPa/orthographic=314.27,7.50,408 which is using the NOAA GFS.
Zooming in on MeteoEarth and comparing with the Turkish Mediterranean site, http://212.175.180.126/DTS/sea.php, it is clear that there is significant loss of detail in the output.
On average, the ECMWF model on MeteoEarth should out-perform the GFS on Earth Wind Map although whether it does so on any particular occasion will be a matter of chance. Both look to be good teaching tools. Both give fascinating views of the atmosphere. Neither seems to me to be of any great use in practical terms to a sailor.

I have used the "weather track" app on my iPhone for over a year. It imports Gribs seamlessly. I know it is also available on the iPad. Perhaps a MAC?
