Marine Weather Forecasting-Masters Class

Coastal & Offshore Marine Weather Forecasting

Coastal and offshore cruising requires many skills. Regardless of where your adventures take you, no aspect of cruising is more important than an understanding of marine weather forecasting. Attendees at the two-day Coastal & Offshore Marine Weather Seminar will develop an understanding of basic weather principles and learn a wide variety of simple forecasting skills that will improve their cruise planning and reduce the likelihood that they will be exposed to uncomfortable or hazardous weather conditions.

What you can expect to learn at the 2-day seminar:

  • A few basic meteorological principles.
  • How to decode the confusing symbols and meteorological shorthand on forecast graphics, regardless of your cruising grounds
  • How to prepare a detailed wave height forecast and recognize the conditions that promote dangerously high waves.
  • Why the wind behaves the way it does and how to prepare a detailed wind forecast.
  • How to predict the development and movement of low pressure systems and their accompanying frontal boundaries.
  • How to forecast the potential of thunderstorms, including when, where, and what type of storms may develop.
  • Identify the ingredients required for the formation of tropical cyclones and how to interpret the products published by the National Hurricane Center.
  • How to use Doppler weather radar and satellite imagery to help you avoid an encounter with severe or hazardous weather.
  • Where to find forecast graphics and a strategy for preparing a multi-day marine forecast.
  • The pros and cons of several of popular weather forecasting apps.

But most of all, the seminar will provide you with the skills to be self-reliant. The seminar combines classroom instruction, case studies, hands-on forecasting exercises, and live product demonstrations to create an engaging learning experience.
