Are you drowning in GRIB files and model options?


Over the past year, marine weather forecasting has experienced a seismic shift. Between the rapid rise of public and private AI-driven forecasting tools and major updates to traditional global models like the GFS and ECMWF, sailors have more data at their fingertips than ever before.

But more data doesn't always mean better decisions. Often, it just means more confusion.

If you are struggling to figure out which models to trust, when to use them, and how to make sense of conflicting forecasts, you are not alone. Weather Models Masterclass: Navigating Today's Data Storm is designed to cut through the fog.

Building on the foundations of Class 7 and Weather Forecasting & AI, this advanced masterclass will help you decode the modern weather landscape so you can choose the best tools for your next race, passage, or camping trip!


What You Will Learn:

  • The Current Landscape (circa Spring 2026): MWU's wx guru, Chris Bedford presents a comprehensive and clear breakdown of today's offerings: the "traditional" models, the new AI players, and private-sector offerings.
  • Model Selection: Chris explains best practices that he uses to incorporate these new models into his workflow - including how to choose the right models to consider based on your location, time horizon, and needs.
  • Signal vs. Noise: Tips on how to move forward when the models disagree and how to find and identify the most trustworthy data.
  • Forecasting and Tactical Application: How to confidently integrate these new tools into your own forecasting and weather routing to gain a competitive edge.

Stop getting lost in the data storm. Learn how to navigate this new era of weather models!





Your instructor: Chris Bedford


Like all of Marine Weather University's weather curriculum - this course is created and taught by legendary meteorologist, Chris Bedford. To say Chris is one of the best marine meteorologists in the world would not be an understatement. He recently led the weather team that guided the Ultime, SODEBO to set (on January 25, 2026) the Jules Verne Trophy Record - around the planet non-stop in 40 days under sail! He's supported 11 America's Cup teams and worked for Olympic teams, Round the World Race events and campaigns. He is one of the most in-demand forecasters in the world of sailboat racing.

Chris is known for his straight-forward, honest, and practical approach to using weather knowledge as a competitive advantage. He obtained his Meteorology degree at the University of Michigan and is highly regarded in his field, having served as President of the National Council of Industrial Meteorologists and on many professional boards and committees including the American Meteorological Society,

Chris' partner in Marine Weather University - 2x America's Cup winner, Peter Isler helps out in the classroom.




This Advanced Class has a Prerequisite!


Weather Models Masterclass is an advanced class that builds on the knowledge taught in MWU's full length courses (Advanced & Fundamentals).

To ensure students get the most out of this new class we are requiring Class #7 as a minimum prerequisite.

If you are already enrolled in MWU's Advanced or Fundamentals Course - you meet this prerequisite and can enroll in Weather Models Masterclass here.

For students that need to meet the prerequisite - MWU is providing three different "bundle" options. They are all great deals offering a discount on the bundle.

IF YOU DON'T MEET THE PREQUISITE - CHOOSE A BUNDLE!

We always encourage new students interested in marine weather to strongly consider enrolling in one of our full-length courses with the special discount offer included in these bundles. At a minimum, to enroll in Wx Models Masterclass you will need to bundle with Class #7.

Please play fair - students that enroll directly in this class without meeting the minimum class prerequisite will be unenrolled and have their tuition refunded.
