Great Lakes Basic Marine Weather Clinic

Great Lakes Basic Marine Weather Clinic

Learn a little weather forecasting and reduce the uncertainty of boating on the Great Lakes. An enhanced understanding of basic weather principles and a few simple forecasting skills can improve cruise planning, racing performance and reduce the likelihood of being exposed to uncomfortable or hazardous weather conditions. A few of the skills you will learn at the clinic:

  • Improve your decision-making for family outings.
  • Enhance your confidence in planning long-distance journeys.
  • Improve your racing performance.
  • Reduce the likelihood of being exposed to uncomfortable or hazardous weather conditions.

What you can expect to learn at the seminar:

  • How to decode the confusing symbols and meteorological shorthand on forecast graphics.
  • How to predict the development and movement of low pressure systems and their accompanying frontal boundaries.
  • Why the wind behaves the way it does and how to prepare a detailed wind forecast.
  • How to forecast the potential and nature of severe weather.
  • How to use Doppler weather radar to help you avoid a hair-raising encounter with a thunderstorm.
  • Where to find forecast graphics and a strategy for preparing a multi-day marine forecast.

The clinic combines traditional classroom instruction, case studies, and exercises to create an engaging learning experience.

Comments From Previous Seminars

  • Best weather seminar ever!!! My husband is a licensed captain and has attended several as well as basics in his classes and testing and in the 60 years he's been sailing.... He said it was, by far, the best weather seminar he has ever attended. 
  • I just wish I had half the knowledge Mark does! He's incredibly well-versed in both the topics of weather AND sailing, and I really enjoyed listening to him, not to mention I learned quite a bit as well!
  • I took your Great Lakes course at the Sandusky Sailing Club probably five years ago and still draw on the knowledge I learned there - you are a very good teacher of a complex topic.  We now live on our sailboat full time and cruise the Atlantic coast from the Bahamas to Maine.
