Whatʹs Great
1. LuckGrib provides access to many weather and ocean models, including: GFS, GDPS/GEM, GEFS, WW3, HRRR, RAP, NAM, NBM, Icon-EU, Arpège, Arome, OpenWRF, RTOFS, NCOM and many others.
2. Sailors have access to two Weather Routing systems: an automated isochronal system to find optimized paths through weather systems, along with a manual system for planning long passages.
3. Weather forecast data, packaged as GRIB files, can be downloaded directly from the LuckGrib server cluster.
4. Access to the isochronal weather routing system requires an in-app purchase.
5. The LuckGrib weather routing system is high quality, robust, high performance and comprehensive.
6. In addition, LuckGrib allows you to explore weather model uncertainty with its support for standard deviation and probability values.
7. Weather Routing will improve your understanding of the weather systems you sail in, through tools such as the analysis images, meteogram and ability to explore the isochronal solution space.

What does LuckGrib do? LuckGrib is a fully featured, easy to use, fast GRIB reader, viewer and downloader. Remote access to weather data via satellite or email is supported. Advanced weather routing capabilities, for sailors, is also available. Weather forecast data, packaged as GRIB files, can be downloaded directly from the LuckGrib server cluster. Downloads are available via: a direct high speed internet connection, through the Iridium GO!, through the RedPort Optimizer, or via one of the various email services (for example: MailASail, UUPlus, XGate or SailMail.) LuckGrib provides access to many weather and ocean models, including: GFS, GDPS/GEM, GEFS, WW3, HRRR, RAP, NAM, NBM, Icon-EU, Arpège, Arome, OpenWRF, RTOFS, NCOM and many others. These models allow you to study surface conditions, wave and swell state, ocean currents as well as higher altitude information such as that found at the 850mb, 500mb and 250mb levels. In addition, LuckGrib allows you to explore weather model uncertainty with its support for standard deviation and probability values. LuckGrib is a thoroughly modern and advanced GRIB viewer. All direct high-speed internet data downloads are free. You have access to over 50 weather and ocean models. See: luckgrib.com/models for more details on the models and parameters that are available. LuckGrib comes with a 14 day free trial. If you are interested in studying weather and gaining access to detailed weather forecasts, download the app and give it a try. Downloading data via satellite or email requires the Offshore Data in-app purchase. The Offshore Data system provides the best compression available. Better compression leads to smaller files. Smaller files, along with an optimized transport protocol, results in faster, more reliable direct downloads. See offshore.luckgrib.com for more details on the remote access capabilities. Sailors have access to two Weather Routing systems: an automated isochronal system to find optimized paths through weather systems, along with a manual system for planning long passages. Weather Routing will improve your understanding of the weather systems you sail in, through tools such as the analysis images, meteogram and ability to explore the isochronal solution space. The LuckGrib weather routing system is high quality, robust, high performance and comprehensive. See routing.luckgrib.com for more details. Access to the isochronal weather routing system requires an in-app purchase. Note that LuckGrib does not use a subscription pricing model - after the free trial, when you decide to purchase the app, there will be a one time charge, not an ongoing subscription.

Excellent and beautiful
This wonderful app lets you retrieve, manage, and display GRIB files (weather forecasts). It's well-written, the author is very responsive and personable, and it looks gorgeous. I bought it a month or so ago and asked for a legend for values -- you can roll over points on the screen to see a detailed list of the attributes at that point which can include anything from temperature at the surface to dew point high up in the atmosphere, but when looking at the map as a whole I thought a legend would be helpful, and voila, it appeared in the latest update. Trying to predict the weather from this professional-level data isn't super easy, but it's a very fun hobby. I'm not a sailor, and for offshore sailboat people I'd say this app is an essential.
Gives me the weather data I need offshore to stay safe
I have been sailing around the world for the past 5 years using every grib viewer for the Macintosh and this is the best one out there. Not only is it fast at downloading and displaying the grib data but it also displays it more accurately than any other viewer. The developer has a background in mathematics and graphics and it shows in the care and construction of this application. When you understand how he interpolates the grid data to provide and smooth and accurate distribution between points you can appreciate his effort to get everything correct.
Got it right.
I was doing some software development with large GRIB files downloaded directly from NOAA and using LuckGrib to check my work that I was reading the files correctly. After some painstaking work I confirmed that LuckGrib and my software were in agreement. That is, they had the correct data at the correct latitude longitude. On the other hand, another GRIB viewer, from a well known commercial company, failed on these full size files. It showed 5 knots wind, where there should have been a hurricane! So now, LuckGrib is my go-to GRIB viewer. Good work Craig.
Well featured, fast, gorgeous
I've used various GRIB viewers on Macs (including Zygrib, OpenCPN, qtVLM, seaIQ, IDV, PredictWind, McIDAS-V, and others) and lots of web sites for weather analysis. LuckGrib quickly became my go-to for most work. It has it's own service for many weather models and can import GRIBs from NOAA or other sources. It handles the non-Mercator projections used by the NAM, RAP, and HRRR. Comparing trends from multiple model runs is easy. It's very fast, even with large data sets. The UI is very smooth and overall easy to use. And I find the output style very attractive (though that may be just me). Well worth the price.
