Weather Briefing
LIFRRennes-Saint-Jacques Airport is currently reporting low IFR (LIFR) conditions with clear skies and 0.5 km visibility.
Wind Analysis
Winds are from the northwest (320°) at 4 knots.
Visibility & Ceiling
Visibility is severely reduced to 0.5 km, likely due to fog, mist, or precipitation. Special VFR or an IFR clearance may be required. Skies are clear with unlimited ceiling.
Temperature & Moisture
Temperature is 5°C (41°F) with a dewpoint of 4°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. 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, Fog, Showers Rain. There is a 40% probability of IFR conditions with Mist between 01:00Z and 06:00Z. There is a 30% probability of LIFR conditions with Fog between 03:00Z and 06:00Z. Temporary IFR conditions are forecast with Showers Rain between 08:00Z and 13:00Z.
Pilot Recommendations
Current conditions require an instrument rating, IFR-equipped aircraft, and an IFR clearance. Check approach minimums carefully as conditions may be below CAT I ILS minimums. 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 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.
