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.This is a small release, with a few minor changes and fixes.
• fixed a defect where the weather routing download sailing angle limit was always interpreted as being true degrees.
• enhanced the weather routing polar import method to allow comma as the decimal symbol.
• provided support for upcoming HRRR model enhancements (smoke, sub-hourly wind data.)
• a fix for a problem when scroll bars were always being shown, the GRIB color legend may have overlapped them.
• a couple small changes to improve the app appearance on BigSur.
