Kualanamu International Airport is the third largest and second busiest airport in Indonesia serving around 16-18 thousand passengers per year. The location of the East Coast of North Sumatra which is directly adjacent to the Malacca Strait indicates that there is an interaction between the atmosphere on the mainland of the East Coast of North Sumatra and the atmosphere in the waters of the Malacca Strait which is represented through the occurrence of land-sea breeze circulation on the East Coast of Medan which is one of the important elements that must be considered. in conducting analysis and weather forecasting in the East Coast region of North Sumatra. Weather information is needed in flight operations, because it is related to the smoothness of the aircraft from take off to landing and flight safety. This research focuses on 3 Meteorological factors that are important in the take-off process as well as landing, namely wind data, rainfall, and visibility. Wind data is processed using the WRPLOT application and the percentage of wind components is calculated. The wind components are headwind, tailwind, and crosswind. Rainfall and visibility data were processed and the percentage of events below the flight safety limit was generated. Research related to wind components, rainfall, and visibility on the Kualanamu International Airport runway used hourly data from Kualanamu Meteorological Station from 2013 to 2022. By referring to runway R23 as the landing direction, it is known that the headwind component has a percentage of occurrences bigger in the MAM season while tailwind in the DJF season. From the calculation of the wind component as a whole, the percentage of wind data that has a headwind component is 26.1%, tailwind is 24.6%. the crosswind component coming from the left is 25.3% and from the right is 24%. This study shows that rainfall is included in the medium category which ranges from 100 – 200 mm/month with as much as 25.8% visibility below the threshold of all data.
