1. A method of controlling irrigation, the method comprising:

  • obtaining a barometric pressure (BP) profile corresponding to changes in BP over a period of time and corresponding to a location where irrigation is to be controlled;

    determining a dew point factor (DPF) profile as a function of changes in temperature and relative humidity over the period of time and corresponding to the location where irrigation is to be controlled;

    making a determination that a rain event is likely to occur as a function of both the BP profile and the DPF profile; and

    generating, based on the determination that the rain event is likely to occur, a control signal configured to cause one or both of current and scheduled irrigation to be limited.
