An irrigation control system and method for controlling irrigation based on weather data. Weather data such as wind, temperature, solar radiation, humidity, and rainfall, may be collected at one or more weather stations for a region. The weather data may be compiled on a computer and transmitted to a paging broadcast service. The weather data may then be transmitted by the paging broadcast service to controller interfaces associated with irrigation systems throughout the region. The controller interfaces may adjust irrigation controllers associated with the irrigation systems based on the weather data such that the proper amount of water is applied. This allows the water to be used more efficiently and the health of the landscape to be improved.
