Where the wind is strong enough to lift sediment of the beach dunes may form which adds stabilisation to the spit when pioneer plants such as marram grass anchor the sand. Alternatively, it could be because the wind and wave front are frequently at an opposing angle to the prevailing wind, generating short periods of longshore drift in the landward direction. Orographic precipitation, rain, snow, or other precipitation produced when moist air is lifted as it moves over a mountain range.
