Weather Briefing

MVFR

Kualanamu International Airport is currently reporting marginal VFR (MVFR) conditions with scattered clouds at 1,900 feet and 5 km visibility.

Wind Analysis

Winds are from the south (180°) at 3 knots.

Visibility & Ceiling

Visibility is 5 km, below VFR minimums in some airspace classifications. Check local requirements before departing VFR. No ceiling exists. Cloud layers reported: scattered at 1,900 ft.

Temperature & Moisture

Temperature is 25°C (77°F) with a dewpoint of 24°C. The temperature-dewpoint spread is very narrow, indicating saturated or near-saturated air. Fog formation or low cloud development is likely.

Forecast Outlook

The TAF forecast covers the next 24 hours. Conditions are expected to fluctuate between VFR and MVFR. VFR pilots should be prepared for deteriorating conditions. Expected weather includes: Haze.

Pilot Recommendations

VFR pilots should exercise caution. Consider filing IFR if instrument rated, or postponing the flight if conditions are expected to deteriorate further. The narrow temperature-dewpoint spread creates risk of fog formation, particularly during evening and early morning hours.

This briefing is generated from real-time METAR and TAF data. Always verify with official sources before flight.

About Kualanamu International Airport

Overview

Kualanamu International Airport serves as the primary international airport for Medan, located in North Sumatra, Indonesia. Positioned at 3.637847°N, 98.870566°E, the airport provides critical air transportation infrastructure for the region, with its large airport classification supporting both domestic and international commercial operations.

Flying Conditions

The airport's low elevation of 23 feet mean sea level (MSL) indicates a relatively flat terrain environment typical of coastal Indonesian regions. Pilots should anticipate potential humidity and tropical weather patterns characteristic of the equatorial climate, which can produce rapid meteorological changes and occasional convective activity.

Notable Features

The airport features a single substantial runway (05/23) measuring 12,303 feet in length, constructed with asphalt and concrete surface materials. Its extended runway length provides significant operational flexibility for various aircraft types, supporting wide-body international and regional aircraft movements.

Approach Considerations

Given the runway's 05/23 orientation, approach and departure paths will be aligned approximately along the east-west axis. The substantial runway length of 12,303 feet offers considerable margin for safe operations, accommodating diverse aircraft performance characteristics and providing extended landing and takeoff capabilities.
