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 a specialized 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.
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.
This software is a top sofware product. As a weather hobbyist for many years, I've experimented with windows and linux-based sofware to view weather grib files. But I wanted something that was easy to use, flexible and provide beautiful graphics. This product does the trick! It has most of the weather models that you will want, free data downloads that are fast and data that is up to date!With this software you can easily and accurately get the model forecast data for your exact location, day by day and hour by hour. Want to know the temperature at 3:31 PM? It will tell you! The developer clearly takes pride in his software and has been readily available to answer the few questions that I had. It comes with a 14 day free trial...once you try it, you'll love it. Glad I found this! Highly recommended!
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.
pros: somewhat simple to use, video tutorial with no sound cons: relative high cost $20 for basic grib viewer, best to be used for planning a trip BUT not actually underway since no GPS or chart import capability conclusion: not for most sailors who need to use app to see & follow their position real time. save the $20 toward more capable apps. ocean sailing experience: 15 years other apps used: sail grib WR android free & paid version, MX Mariner android free & paid version suggestion to developer: offer a free basic version for trial use
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.
If you are a weather enthusiast and are looking for an app to take it to the next level, look no further. This is what you have been waiting for!
If you are looking for a grib viewer or even just a way to look at an incredibly wide array of weather data look no further. This program is head and shoulders ahead of what else is out there; it has everything from GFS to HRRR to ASCAT. Simply Awesome.
The professional tool I was looking for. Thanks
First off, the software creator, Craig, is awesome. Before purchasing this app I sent him an email asking a couple questions and he responded almost immediately. Second off, this is hands down the best grib viewer for Mac. I spent quite a bit of time trying to port grib viewers from Windows/Linux on to Mac and I spent quite a bit of time trying to find one that was natively supported by Mac. Long story short, I stumbled across this gem. I have rougly 10 years of forecasting experience for aviation and remote expeditions. I would like to note that I do not have a sailing background, which is what this app is focused towards. However, for what I do this app is amazing. It’s fast and efficient, and the software developer is quick to respond to any issues. There is a pretty extensive list of things you can do as far as creating your own styles and color schemes and if you have a meteorological background then this app is for you.
I happen to be in my final semester of school in the pursuit of a Meteorology degree at Virginia Tech. I have gone through the weather classes really just trying to make good grades and get my credentials (As most college students do). I had the mentality of someone who’s only focus was that GPA. This is a very different goal than LEARNING to the best of my ability (which is what I should have been doing all along). I think the issue with me is that I was unable to really develop a true appreciation for this field. After using this pristine piece of software, I found myself just playing around and trying my hand at forecasting. The way that this program uses interpolation, in my opinion, is the best part about it. I can’t even imagine the amount of work that these people put into this program. Because of that, I feel that what you are actually getting for only 20 dollars makes the decision to purchase this warranted - if not imperitive for someone with ANY interest in weather phenomena. This is an incredible tool, and it requires you to take the time to understand the different variables and how they relate to weather. This is work, but once things slowly begin to click mentally, you begin to develop insight into just how powerful this product is. I also think that we should take some time to appreciate the fine humans who distribute the incredibly vast amount of weather data for free. We live in an incredible world with incredible technology allowing us to think on a level that seemed unimaginable a very short time ago. If you are intersested in weather for any reason, you are simply missing out if you don’t give this a try!
