Description

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.

For offshore sailors, LuckGrib offers a best-in-class, complete solution: industry leading visualization and ease of use, highly optimized weather data downloads via satellite, along with industry leading optimized weather routing and route analysis. Inshore sailors may not require satellite downloads, but will benefit from the rest of the system.

LuckGrib is unique among apps that were originally designed for sailors, in that the weather analysis tools are powerful enough to attract attention from meteorologitsts.

For meteorologists, and weather enthusiasts, LuckGrib offers access to a wide range of high resolutions models, a number of global models, weather data at the surface, 850mb, 500mb and 250mb levels, parameters ranging from simple things such as wind, pressure and temperature, to more advanced quantities such as simulated radar, standard deviations, precipitable water, lightning, vertical vorticity, helicity and more. Access is available to the entire suite of parameters in GFS, HRRR, NAM and others.

Downloads are available via: a direct high speed internet connection, through the Iridium GO! as well as through the RedPort Optimizer.

LuckGrib provides access to many weather and ocean models, including: GFS, GFS Wave, GDPS/GEM, GEFS, 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, winds at the jet stream level, mid atmosphere as well as at the boundary layer. 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.

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. See offshore.luckgrib.com for more details on the remote access capabilities.

The LuckGrib weather routing system is an industry leading, high quality, robust, high performance and comprehensive system. See routing.luckgrib.com for more details. Access to the isochronal weather routing system requires an in-app purchase.

The LuckGrib isochronal Weather Routing solver is able to respect intermediate constraint points, the first in the industry. A constraint point is a point which a route must leave to port or starboard. Constraint points are needed to describe short routes which have crossings, as well as to express your preference on a long open ocean passage to stay to a given side of a strategic point. A simple example of a short route that needs this ability is a route which goes around an island, returning to the start point. Many sailboat race routes, perhaps the majority, have routes which cross. Two examples are Fastnet and the Around Catalina Island race. These routes can now be described in LuckGrib, and optimized Weather Routing solutions found for them.

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.

Worth Every Penny

The layout, tutorials...everything is so intelligent and user friendly. For beginners, it’s almost like taking a basic meteorology course. More thought was put into this than any other app I’ve ever used.
I’ve used some free grib software and tried other 3rd party analysts online, and this is the best thing I’ve found. People actually use this for crossing oceans. Just get a meridian transmitter and an iPhone. 20$ is way better than spending 2000$ on one of those hardcore systems you have climb the mast to install. Sure there’s no substitute for onboard weather radar but that gear is $$$.
I live very close to a NOAA building, and actually went in to get someone to show me how to use their website, and I still couldn’t figure it out. They DO NOT have an app. Don’t be fooled. Nor do they have a mobile website.
As far as accurate data is concerned grib files are where it’s at, and this is simply the best mobile option.
People go out on the ocean all the time without being smart and checking the weather. They leave at the crack of dawn when it’s not blowing. By late afternoon they’re 20 miles out, caught in a gale, calling for help. In the age of the smartphone there’s no excuse. This app saves lives.

Long time user

I’ve been using LuckGrib since it’s early days and it is remarkable to see how it has developed into what I think is the best weather solution for boaters available for iOS. The developer is very responsive to feedback. I don’t know how he would respond to bugs and problems because I haven’t seen any of those, yet. I’m guessing pretty good! I’ve used the weather routing features on several long passages, and it has changed the way I think about weather windows for the better. The app’s integration with Iridium Go is second to none. The number of available models is likewise outstanding. Finally, as an iOS developer myself, I have to take my hat off to the app’s user interface which is elegant and intuitive in the way that all apps should be, but often are not. Highly recommended.

Essential

The essential tool for outdoor activity planning. GFS, NAM, HRRR give the picture that becomes more precise closer you get to your planned time. The app let me ride through 60miles bike ride event in the rain dressed properly, as I knew the rain won’t end, and it will rain on the whole route. I wish there was support for experimental HRRR smoke model. UPD having an address converter instead of having to enter coordinates would also make the app more usable.
