Great Lakes Wind Forecasting

Great Lakes Wind Forecasting

No aspect of weather is more important to sailors than the wind. It dictates when it is safe to leave port and whether your journey will be fast or comfortable. On the race course, properly predicting the wind separates the winners from the losers.

This 4-hour clinic is designed for sailors of all experience levels and interests. Accurately forecasting the wind promotes safer, more enjoyable outings and improves performance on the race course. Whether you are a day sailor, long-distance cruiser, beer-can racer, or serious competitor, the skills learned during this 4-hour clinic will enhance your understanding of the wind and improve your sailing experience.

What you can expect to learn at the clinic:

  • Why the wind behaves the way it does.
  • The impact of high and low pressure systems on the wind.
  • How to translate the confusing symbols and meteorological shorthand on weather forecast graphics.
  • The basics of lake breezes, land breezes, thunderstorms, clouds and other dynamics that produce localized and short-term changes in the wind.
  • A routine for observing the wind and using on-line resources to develop your own forecast.

The clinic combines traditional classroom instruction, case studies and several hands-on forecasting exercises to create an engaging learning experience.

Comments From Previous Seminars

  • I thought the Great Lakes Wind Forecasting was a great in-depth look at weather and forecasting, some of it was review, but so much of the program gave me a greater understanding of the elements of a forecast that I'm looking at. It was great!
  • I have attended many workshops and I can say yours ranks at the top. The material covered and your way of presenting it made for a great day.
  • What a great seminar on weather and wind forecasting at the BCYC. Mark did such a good job helping me plan our day on the water. If you are new to sailing/boating or an old salt this will benefit your sailing experience. I'll certainly be at the next seminar! Thanks.
