There are only a few farms in the Overberg region in South Africa with a sophisticated weather station. Elandsvalley Farm, home of Stanford Valley, is one of these. The station keeps track of humidity, atmospheric pressure, precipitation and feeds the farmer’s computer with all these data. Based on these data and (sometimes) combined with data from other weather stations, including satellite observations, it’s possible to plan the work (sowing, etc.) a few days ahead.
Most of the time the forecast is quite accurate. But ever heard of a weather forecaster who has got it always right?
