Weather Briefing
IFRSeosan Air Base is currently reporting instrument flight rules (IFR) conditions with broken clouds at 500 feet and 4.8 km visibility. Note: This observation is 1179.1 hours old and conditions may have changed.
Wind Analysis
Winds are from the south-southwest (210°) at 5 knots. Runway 21 is favored with a 5-knot headwind and 0-knot crosswind component.
Visibility & Ceiling
Visibility is reduced to 4.8 km. IFR conditions prevail and an instrument clearance is required for operations in controlled airspace. The ceiling is 500 feet AGL (broken). Only precision approaches may be usable depending on minimums.
Temperature & Moisture
Temperature is 6°C (43°F) with a dewpoint of 5°C. The temperature-dewpoint spread is very narrow, indicating saturated or near-saturated air. Fog formation or low cloud development is likely.
Pilot Recommendations
An instrument rating and IFR flight plan are required. Verify that destination and alternate approach minimums are above current and forecast conditions. 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 Seosan Air Base
Seosan 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.
Seosan Air Base (RKTP/HMY) is located in Seosan, KR at an elevation of 39 feet MSL. The airport has 2 runways (03L/21R, 03R/21L), with the longest at 9,000 feet.
Weather Profile
RKTP is weather-challenged, with VFR conditions just 42.4% of the time across 455 observations. IFR/LIFR conditions are present 34.5% of the time, making an instrument rating essential for reliable access.
Wind Patterns & Runway Selection
Prevailing winds at RKTP come from the S (180°) with an average speed of 5 knots. Calm winds are rare (0%), so crosswind considerations are a regular factor. Runway 03L/21R offers the lowest average crosswind component at 2.8 knots, making it the preferred choice in typical wind conditions.
Seasonal Considerations
The best months for VFR operations are November, January, December, when clear skies are most prevalent. Temperatures at the field range from -10°C (14°F) to 29°C (84°F), averaging 8.3°C (47°F). Altimeter settings typically range from 29.61 to 30.49 inHg (1003-1033 hPa).
