Kuala Namu International Airport (KNO) serves Kuala Namu, Indonesia, and lies approximately 21 miles from the city center. The airport sits at a low elevation of 35 feet above sea level, placing it in coastal lowland terrain typical of much of northern Sumatra.

Given its modest elevation, Kuala Namu International Airport operates in a tropical setting where heat-driven convective weather is a regular feature of daily flight operations. Travelers using this airport should be aware that low-lying coastal airports in this region can experience afternoon thunderstorm activity, which is a normal part of the local climate pattern rather than an unusual occurrence. The airport's position near sea level also means it is less affected by the terrain-induced turbulence sometimes associated with airports at higher elevations or in mountainous surroundings.

The distance between the airport and the city it serves is a practical consideration for travelers planning ground transportation connections before or after their flights. At 21 miles, this places Kuala Namu International Airport at a moderate remove from the urban center, a layout common to airports built to accommodate larger aircraft and expanding air traffic away from dense city cores. Passengers should factor this distance into their overall travel time when scheduling arrivals and departures through Kuala Namu International Airport.
