How to make your own accurate weather forecast?

Meteorologists in our days monitor large-scale weather systems and use advanced computers to predict with fair accuracy what lies ahead. But before heading out on the water, you should obtain local forecast and make your own update on board.

Regional forecasts do not always match actual conditions on the water because they cannot account for variations across the region of coverage. On the one hand on land it barely matters if the actual wind is 12 of 25 knots, but on the water, is certainly does. On the other hand, topographically enhanced sea breeze or locally generated thunderstorm cannot be accurately covered by regional forecast. Even forecasts for offshore waters due to the lack of monitoring stations can be several hours out of date by the time they reach you.

You will be better prepared if you use your own observations in combination with official forecasts.


  • The Weather for Sailors webinar objective is to teach sailors how to gather and interpret official weather information
  • How to combine this information with own observations and create a refined forecast
  • How to apply that weather forecast to sailing or racing

You will learn

Our webinar will help you to better understand the kind of weather you can expect while sailing, whether you are reading a weather map or making your own observations.

Basics of the forecasting

  • Weather proverbs. For centuries sailors have come up with a lot of proverbs related to the weather, in which they interpret their observations. We will look at them to find why they have proven their reliability
  • Fronts and storms formations
  • Determination of cyclones and anticyclones. Why is it important? Rule of Base Ballo
  • Clouds formations. Making your own forecasts based on visual observations of the changing clouds

Personal weather forecast

  • Don't spoil your vacation! Katabatic winds and their impact on navigation
  • Where can I get reliable weather report? Weather forecast via VHF radio, receiver NAVTEKS and the Internet
  • How to make your own weather forecast. Using a barometer, thermometer, and visual observations


  • How to escape the storm? Basic scheme and how to use it in practice
  • Storming. Preparation of the boat for severe weather conditions. Storm Guard rails, sail, sea anchor to help boaters

Different navigation zones

  • Navigation conditions in Thailand, the Maldives, the Seychelles and the Caribbean
  • Climatic features: breezes, monsoons, typhoons, the trade winds
  • The concept of the windward and leeward islands
  • Winds and navigation conditions when sailing between islands
  • Windward and Leeward island groups

The above mentioned elements of weather forecasting on board can be combined in various ways in order to get the most accurate information. Let's see what are the main principles of changing weather.
