Campervan 101 in Iceland, a rough guide for beginners.
As always: Iceland has a unique forecasting system. The forecast is only good 2-3 days ahead of time. It is crucial to know how to read the weather, as it could be life or death. Any phone weather app or weather site that is not IMO is probably useless for Iceland, as they typically do not include the very important wind forecasts. Cold and rain you can dress for and get on with your day.
