Using an RC filter on the input may help to reduce the noise or an op-amp active filter may work better as it would give a low-impedance filtered output to the ADC.
Is the output from the wind speed sensor linear or pulsed? If it is pulsed then you could use a comparator circuit to set the input to trigger only above a set limit.
