LuckGrib is a fully featured, easy to use, fast GRIB reader, viewer and downloader
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
LuckGrib uses beautiful and fast graphics to give you insight and understanding into how the weather and ocean conditions will change through a forecast as well as showing you the details of what happens at any location
Weather forecast data, packaged as GRIB files, can be downloaded directly from the LuckGrib server cluster. Downloads from the server cluster are fast - you can easily explore the weather world wide using some of the best weather models available
All data downloads are free. You have immediate access to over 30 weather and ocean models
Weather models are available which contain 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 - these levels correspond to the low cloud level or jet stream, for example. Some of the models available are: GFS, GDPS, CMC, WW3, HRRR, RAP, NAM, NDFD, Icon-EU, OpenWRF, RTOFS
Check the support site for additional information regarding model availability. Short videos are also available, as are tutorials and other information
• designed, built and optimized for iOS while being based on the widely respected macOS version of LuckGrib
• download your data directly from the LuckGrib server cluster
• download weather and ocean data from models created by NOAA, Environment Canada, Météo-France, Deutscher Wetterdienst (DWD) in Germany and OpenWRF
• both global and regional models are available
• high resolution GRIB models are supported and displayed on their native grid (you see the actual model data, not a processed version where there is room for error)
• smooth transitions and animation show how the weather or ocean conditions evolve through a forecast
• instantly updated graphical and textual information as you interact with the weather models
• graphs of weather values (meteograms) at a point or along a line. Meteograms are a convenient way to see trends in the weather
• mark points and name them. Measure distances, simulate traveling through weather
• simple weather and application tutorials
• support for GRIB versions 1 and 2 allows you to import the widest range of information
• import GRIB files from outside sources such as PredictWind, Ocens, Saildocs and many others
• access to hundreds of GRIB parameters (wind, rain, pressure, temperature, CAPE, CIN, humidity, wave information, ocean current data, vorticity, simulated radar, and many more)
• an internet connection is not required to view downloaded files. LuckGrib acts as a fully functional viewer when away from the internet
LuckGrib has a built in GRIB file librarian, allowing you instant access to all of your GRIB files. Switching between GRIB files is very fast, allowing you to compare the results of different models or to watch how a forecast evolves over time
There are a couple of small improvements in this release, including:
• receiving a phone call in the middle of a file download no longer interrupts the progress of the download
• added over 200 new small city names to Europe, and other minor map label adjustments
• added the points position to the point editor. You can now adjust the position by typing in a new value
Ratings and Reviews
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.
Great Grib App
As a sailor and general weather fanatic I find Luck Grib to be filled with unique and useful features. The graphic presentation is outstanding. If you are serious about weather you should have Luck Grib on your side.
This app is amazing!
I am a research meteorologist and this a wonderful, seemingly flawless app for visualizing GRIB data and keeping an eye on the weather. It has exceeded my expectations!
