Online Book:

Weather Reception and Analysis

Includes Free Introductory Chapter (scroll down).

When you have spent twenty years voyaging in the northern North Atlantic and adjacent Arctic waters in an open cockpit sailboat, you learn something about weather, whether you like it or not.

In this Online Book, John takes you step-by-step through the methods he uses to receive weather information while offshore and in remote places. And best of all, the sources and methods he uses are absolutely free. He also shares how to minimize your transmission costs for further savings. None of this is unproven theory. This is the way John “does the weather” on Morgan’s Cloud’s Arctic voyages.

Tips For Receiving Weather Fax


Starting with this chapter I’m going to focus on weather reception tools that we use when we are offshore or in remote places where the internet is not available. Let's start with weatherfax and why it's still important.

Recommended Grib Viewer


In this chapter I’m going to get into the nuts and bolts of the software we use to view GRIB data and make some recommendations.

Tips For Receiving GRIBs


In this chapter I’m going to get into the details of how we request and use GRIBs to get the maximum amount of information for the minimum data size and cost, when at sea or in remote areas with no internet.

How To Look Ahead—Way Ahead


Used correctly, and coupled with some effort to understand high altitude steering winds, GRIBS can be used to predict weather trends a surprisingly long way in the future. And that can substantially increase your enjoyment of cruising. This chapter will show you how.

The Importance Of The Big Picture


In this chapter I'm going to discuss a real world example of how we used the tools we have discussed in this book to manage a weather risk while transiting Hudson Strait and the northern coast of Labrador—no place to get caught by bad weather.

It’s A Forecast, Not A Prophecy


In the last chapter I wrote about the importance of understanding the weather systems in a wide area around you rather than just looking at a GRIB or forecast for your immediate area. I believe this is so important that I'm going to write about another storm to drive the point home.

Managing Ocean Currents

Jenifer's Clark's Gulfstream chart

I have written a lot about weather up to this point in the book, but in many cases routing for the combination of the prevailing weather and any current or tide can be the most important contributor to a comfortable and safe passage. In this chapter I look at a real Gulfstream passage and discuss what to look for.

HF SSB Radio or Iridium Satellite Phone?


What hardware should you buy for receiving weather information and other communications? In this chapter I take a look at the two main options, HF SSB and satellite phone, and make some recommendations.

The Ultimate Guide to Using Iridium Handsets and GO!


The whole process of buying, installing and working with a satellite phone can be downright intimidating and very frustrating. John explains how to make the whole process easy. The results of 15 years of experience with Iridium devices.
