Weather determines when we sail, where we sail to – and whether we arrive safely. This essential pocket-sized guide, now revised for its third edition, provides the reader with all the necessary tools to predict and deal with local and distant weather conditions, whether on a day trip or a longer cruise, along the coast or further offshore.

Each topic is broken down into digestible chapters, explaining the origins and effects of the full spectrum of weather conditions, including:
- using and evaluating weather forecasts
- depressions, fronts, isobars and other coastal effects
- waves and swell
- weather lore and sky watching.

Meteorology is still advancing and sources of forecasts are changing. This new edition keeps the handbook up-to-date, with revised sections and new material on computer weather products, satellite phones, internet access, changes in the availability of forecasts, climate change and the Coriolis effect.

With practical explanations and helpful diagrams and photographs, this is the ideal aide-memoire for skippers and crew, especially those studying for their Day Skipper and Yachtmaster exams.
