Preparation is key to any adventure in the outdoors. This includes checking the weather, packing the right gear, ensuring you have maps, and letting people know where you are going and when you expect to be back.
Checking the weather is always important. Weather forecasting is a prediction of what the weather will be like in an hour, tomorrow, or next week. It involves a combination of computer models, observations, and a knowledge of trends and patterns. By using these methods, reasonable accurate forecasts can be made up to seven days in advance.
Before weather forecasters can tell us what the weather is going to be doing tomorrow, they need to know what it is doing right now. Every hour hundreds of weather stations across New Zealand, from Cape Reinga (Rerenga Wairua ) to Stewart Island (Rakiura), send in reports of how the weather is where they are. As well as telling us how windy it is, how warm it is and how much rain has fallen, the weather stations can also tell us where it is raining or snowing, how much cloud there is, and the pressure of the air.

Think about the basics such as clothing, food, and shelter. Also think about navigation aids such as maps and GPS as well as emergency equipement such a Personal Locator Beacon (PLB) and a First Aid kit.
