The single (31/13) runway is on a similar heading as the close by Hamilton Air Force Base (closed) and Petaluma Municipal Airport (O69) runways, but the prevailing summer afternoon onshore west wind direction and speed at Gnoss Field are changed and amplified by proximity to  Burdell Mountain, just west of the airport.
