Weather Briefing

MVFR

Gunsan Airport / Gunsan Air Base is currently reporting marginal VFR (MVFR) conditions with clear skies and 4 SM visibility.

Wind Analysis

Winds are from the east-northeast (70°) at 3 knots.

Visibility & Ceiling

Visibility is 4 SM, below VFR minimums in some airspace classifications. Check local requirements before departing VFR. Skies are clear with unlimited ceiling.

Temperature & Moisture

Temperature is 17°C (63°F) with a dewpoint of 15°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 26 hours. The forecast shows a transition between VFR and IFR conditions. Pilots should monitor the forecast closely and have an alternate airport plan. Expected weather includes: Mist. Temporary IFR conditions are forecast with Mist between 20:00Z and 22:00Z.

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. The forecast indicates conditions may deteriorate. Ensure you have fuel reserves and a viable alternate airport.

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

About Gunsan Airport / Gunsan Air Base

Gunsan Airport / Gunsan Air Base is a military facility. Civilian access may be restricted or require Prior Permission (PPR). Pilots should consult the KR AIP for current access procedures and restrictions.

Overview

Gunsan Airport, located in southwestern South Korea, serves as a dual-use military and civilian airfield. The airport is situated at a low elevation of 29 ft MSL near the city of Gunsan, providing strategic air access to the region. Its single runway (18/36) spans 9,000 feet and is constructed of concrete.

Flying Conditions

Pilots can expect predominantly favorable VFR conditions, with 71% of observations indicating clear weather and only 3.6% reporting IFR conditions. The airport experiences consistent northerly winds averaging 7.5 knots, with occasional stronger gusts up to 29 knots. Temperature variations are significant, ranging from -8°C to 32°C, with an average of 10.2°C.

Notable Features

The airport's geographic location suggests a relatively flat terrain typical of southwestern Korean coastal regions. With calm wind conditions present 7.2% of the time, pilots should be prepared for potential light and variable wind scenarios. The runway alignment (18/36) demonstrates excellent wind compatibility, with 100% favorable wind conditions and an average crosswind of only 4 knots.

Approach Considerations

November, January, and September represent the most consistent VFR months for operations. Visibility averages 10.3 statute miles, with minimal instances of restricted visibility (below 3SM occurring in only 1.9% of observations). Pilots should note the low probability of fog, which is present in just 1.1% of recorded meteorological conditions.
