An irrigation system that controls the amount of water to be applied based upon specific historical meteorological data including relative humidity, evapotranspiration data, and precipitation. The invention is also of a method for determining the optimal time of day to measure actual relative humidity, and for setting the relative humidity set-point.

[ What is claimed is:] [6.] A method for controlling an amount of irrigation water to be applied to a given area, the method comprising the steps of:a) setting time and duration for at least one irrigation valve to remain open so the amount of irrigation water can be delivered to the given area;b) measuring actual relative humidity;c) setting a preferred time to measure an actual relative humidity value;d) setting a pre-selected relative humidity value;e) comparing the actual relative humidity value to the pre-selected relative humidity value to determine if irrigation water should be applied;f) setting a time differential between the time the actual relative humidity is measured and the time of at least one irrigation valve is scheduled to open; andg) preventing opening of the irrigation valve if the actual measured relative humidity is greater than the pre-selected relative humidity value.
