Wouldn't it be useful to be able to accurately predict the weather simply by reading the clouds? Well, with this book, you can!

TV forecasts, online predictions and smartphone apps are all based on the same data - a number-crunched overview of how air pressure and temperature affect the weather across a large geographical area.

But to get an idea of how the weather will develop for the precise spot where you're standing (or walking, sailing, golfing, fishing, etc) you don't need any equipment or a wifi connection - you just need to look up.

This book will give you a broad understanding of why the clouds are symptoms of weather patterns, not causes. By reading these signs in the sky and referring to the explanatory colour photographs, you will discover exactly what those signs mean.

An at-a-glance guide to the clouds for anyone anywhere in the world, on land or at sea, this book will enable you to predict the weather by recognising cloud types, shapes, colour and behaviour. It will be an invaluable companion for anyone who enjoys outdoor activities.

With a Foreword by Tom Cunliffe.
