Weather Briefing
MVFRMOD St Athan is currently reporting marginal VFR (MVFR) conditions with overcast skies at 1,400 feet and 10 miles or greater visibility.
Wind Analysis
Winds are from the west (280°) at 18 knots. Runway 25 is favored with a 16-knot headwind and 9-knot crosswind component. Student pilots and low-time aviators should exercise caution.
Visibility & Ceiling
Visibility is unrestricted. The ceiling is 1400 feet AGL (overcast), placing conditions in the MVFR category.
Temperature & Moisture
Temperature is 18°C (64°F) with a dewpoint of 15°C. The narrow temperature-dewpoint spread suggests high humidity and potential for visibility restrictions, especially during cooling periods.
Forecast Outlook
The TAF forecast covers the next 22 hours. The forecast shows a transition between VFR and IFR conditions. Pilots should monitor the forecast closely and have an alternate airport plan. There is a 30% probability of MVFR conditions between 14:00Z and 20:00Z. Temporary MVFR conditions are forecast between 20:00Z and 05:00Z. There is a 40% probability of IFR conditions between 21:00Z and 03:00Z.
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.

About MOD St Athan
Overview
MOD St Athan is a military airfield located in the Vale of Glamorgan, Wales, serving Ministry of Defence aviation requirements. Situated at an elevation of 163 feet above mean sea level, the airport provides strategic infrastructure for military aircraft operations in the United Kingdom.
Flying Conditions
The airport's location in South Wales suggests a maritime climate with potential for variable weather conditions typical of the British coastal region. Pilots should anticipate potential wind shifts and precipitation, with the airport's single runway (07/25) oriented to accommodate different wind directions across its 5,997-foot asphalt surface.
Notable Features
The airfield's geographical position near the Bristol Channel introduces potential for complex local terrain and wind interactions. Its medium-sized classification indicates capabilities for supporting a range of military aircraft sizes and operational requirements, with the substantial runway length enabling flexible aircraft handling.
Approach Considerations
Runway 07/25 provides bilateral approach capabilities, allowing landings and takeoffs from both directions depending on prevailing wind conditions. The runway's length of 5,997 feet supports substantial operational flexibility for various military aircraft types, with careful consideration required for local terrain and potential wind gradient effects.
