Byron Airport is a county-owned public-use airport located two miles south of the central business district of Byron, a community in Contra Costa County, California, United States. According to the FAA's National Plan of Integrated Airport Systems for 2007–2011, it is categorized as a reliever airport.
On the lee side of the Diablo Range mountains, Byron regularly experiences variable 10-30 knot winds and thermals in the vicinity. Local student pilots often use Byron to practice crosswind landings. Uncontrolled and relatively isolated, Byron supports organizations for skydiving and soaring. For skydiving, the popular drop zone is on the north end of the airport and serviced by Bay Area Skydiving. For soaring, the Northern California Soaring Association offers instructions on weekends in flying gliders. All pilots should be mindful of the variable wind and thermals, rising terrain, and traffic without radios.
