San Diego International Airport (SAN) serves the city of San Diego, California, and lies just 3 miles from the city center, making it one of the more conveniently placed airports for travelers heading into downtown. Sitting at an elevation of 14 feet, the airport occupies a low coastal position typical of Southern California's Pacific edge.

The airport's traffic mix reflects a strong domestic network across the United States, connecting San Diego with major hubs on the East Coast, the Midwest, and other parts of North America, including destinations in Canada. Alongside this domestic backbone, SAN also supports transatlantic connections to Western Europe, linking the city with major hubs in the United Kingdom and Germany. This combination gives the airport a character that is predominantly domestic in scale but with a meaningful international dimension, particularly toward Europe.

For travelers using Flying Calmly's turbulence forecasts, it is worth noting that flights from SAN often cover long transcontinental distances within North America as well as lengthy oceanic crossings to Europe, meaning conditions can vary considerably depending on the specific route and season. The airport's low elevation and coastal location mean it is generally free from the turbulence concerns associated with high-altitude or mountainous airports, though flights departing toward the east or across the Atlantic may encounter a wider range of atmospheric conditions over their longer paths.
