Weather Briefing
LIFRSaint John Airport is currently reporting low IFR (LIFR) conditions with overcast skies at 300 feet and 3 SM visibility.
Wind Analysis
Winds are from the southwest (220°) at 8 knots. Runway 23 is favored with a 8-knot headwind and 1-knot crosswind component.
Visibility & Ceiling
Visibility is 3 SM, below VFR minimums in some airspace classifications. Check local requirements before departing VFR. The ceiling is very low at 300 feet AGL (overcast), well below circling minimums at most airports.
Temperature & Moisture
Temperature is 2°C (36°F) with a dewpoint of 2°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 12 hours. IFR conditions are expected to persist or develop. An instrument rating and IFR flight plan are recommended. Expected weather includes: Light Rain, Mist, Mist, Light Showers Rain, Mist, FCST. Temporary IFR conditions are forecast with Mist between 06:00Z and 14:00Z. Temporary MVFR conditions are forecast between 14:00Z and 16:00Z. Temporary IFR conditions are forecast with Light Showers Rain, Mist, FCST between 16:00Z and 18:00Z.
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.

About Saint John Airport
Overview
Saint John Airport serves the urban and maritime region of southern New Brunswick, Canada. Located at coordinates 45.316101, -65.890297 with an elevation of 357 feet MSL, the airport is classified as a medium-sized facility supporting regional and commercial aviation. Its strategic position enables transportation connectivity for the Saint John metropolitan area and surrounding communities.
Flying Conditions
Weather conditions at Saint John Airport demonstrate significant variability, with Visual Flight Rules (VFR) predominating at 61.2% of observations. Pilots should anticipate substantial meteorological changes, with Marginal VFR and Instrument Flight Rules conditions collectively representing 38.5% of recorded periods. Temperature ranges from -25°C to 24°C, with an average of 2.9°C, indicating potential icing and thermal fluctuation considerations.
Notable Features
The airport features two asphalt runways: Runway 05/23 at 7000 feet and Runway 14/32 at 5100 feet. Prevailing winds consistently come from the west (270°) at an average speed of 9.5 knots, with maximum gusts reaching 34 knots. Both runways demonstrate 100% favorable wind alignment, suggesting flexible operational capabilities across wind conditions.
Approach Considerations
September, October, and November represent the most favorable VFR months, offering optimal flying conditions. Average crosswind components are moderate, measuring 6.5 knots for Runway 05/23 and 5.8 knots for Runway 14/32. Pilots should be prepared for potential reduced visibility, with 8.1% of observations showing less than 3 statute miles of visibility and 7.2% experiencing fog conditions.
