Weather Briefing
VFRRennes-Saint-Jacques Airport is currently reporting visual flight rules (VFR) conditions with broken clouds at 8,000 feet.
Wind Analysis
Winds are from the east (90°) at 15 knots. Runway 10/28 is favored with a 15-knot headwind and 3-knot crosswind component. Student pilots and low-time aviators should exercise caution.
Visibility & Ceiling
The ceiling is 8000 feet AGL (broken), well above standard VFR minimums. Caution: cumulonimbus (thunderstorm) clouds reported at 8,000 ft AGL, indicating convective activity in the area.
Temperature & Moisture
Temperature is 18°C (64°F) with a dewpoint of 4°C, indicating relatively dry conditions.
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: Light Showers Rain. Temporary VFR conditions are forecast between 12:00Z and 14:00Z. There is a 30% probability of MVFR conditions with Light Showers Rain between 12:00Z and 16:00Z. Temporary VFR conditions are forecast between 10:00Z and 12:00Z.
Pilot Recommendations
Conditions are favorable for visual flight. The forecast indicates conditions may deteriorate. Ensure you have fuel reserves and a viable alternate airport.

About Rennes-Saint-Jacques Airport
Overview
Rennes-Saint-Jacques Airport serves the Brittany region in northwestern France, located near the city of Rennes in Ille-et-Vilaine. As a medium-sized airport with an elevation of 124 feet MSL, it provides critical aviation infrastructure for regional and commercial operations. The airport features two asphalted runways capable of supporting diverse aircraft types.
Flying Conditions
Weather conditions at Rennes-Saint-Jacques demonstrate significant variability, with visual flight rules (VFR) conditions present 36.7% of the time and instrument conditions (IFR/LIFR) occurring 41.4% of observations. Temperature ranges from -6°C to 29°C, with an average of 10.3°C, indicating potential seasonal temperature challenges. Prevailing winds from the south (180°) average 7.8 knots, with occasional gusts up to 26 knots.
Notable Features
The airport's two runways offer flexibility for different wind conditions, with both 10/28 and 14/32 experiencing 100% favorable wind alignments. Crosswind components remain relatively moderate, averaging 5-5.6 knots across runways. The airport's location in Brittany suggests potential maritime weather influences and complex local terrain interactions.
Approach Considerations
Pilots should anticipate mixed meteorological conditions, with fog occurring in 13.4% of observations and average visibility around 10 statute miles. September through November represent the most consistently favorable VFR months. The longer runway 10/28 at 6,890 feet provides substantial landing and takeoff options for most aircraft types.
