Weather Briefing

VFR

Sherbrooke Airport is currently reporting visual flight rules (VFR) conditions with few clouds at 6,600 feet and 8 SM visibility.

Wind Analysis

Winds are from the northeast (50°) at 8 knots. Runway 13/31 is favored with a 1-knot headwind and 8-knot crosswind component.

Visibility & Ceiling

Visibility is 8 SM. No ceiling exists. Cloud layers reported: few at 6,600 ft.

Temperature & Moisture

Temperature is 10°C (50°F) with a dewpoint of 10°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 3 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: Light Rain, Light Showers Rain, Mist, FCST, FCST. Temporary IFR conditions are forecast with Light Showers Rain, Mist, FCST, FCST between 00:00Z and 03:00Z.

Pilot Recommendations

Conditions are favorable for visual flight. 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.

This briefing is generated from real-time METAR and TAF data. Always verify with official sources before flight.

About Sherbrooke Airport

Overview

Sherbrooke Airport serves the Estrie region in southeastern Quebec, providing critical aviation infrastructure for the area. Located at an elevation of 792 ft MSL, the airport offers medium-sized airport capabilities with two substantial runways capable of handling diverse aircraft operations. Its strategic positioning makes it a key transportation node for regional and general aviation activities.

Flying Conditions

Pilots can expect variable weather conditions, with marginal VFR (MVFR) conditions predominating at 45% of observations. The airport experiences significant temperature range from -29°C to 28°C, requiring careful pre-flight planning and potential winter operations considerations. Wind patterns are predominantly westerly at an average of 7.3 knots, with maximum gusts reaching 31 knots and calm conditions occurring 9.2% of the time.

Notable Features

Both primary runways (13/31 and 14/32) are identically long at 6000 ft with asphalt surfaces, providing robust operational flexibility. The airport demonstrates excellent wind alignment, with both runways showing 100% favorable wind coverage and manageable average crosswind conditions (4.7-5.3 knots). Visibility averages 7.1 statute miles, with limited periods of reduced visibility (below 3SM occurring in 6.9% of observations).

Approach Considerations

September, October, and January represent the most consistently favorable VFR months for operations. Pilots should anticipate potential IFR conditions (10% of observations) and be prepared for occasional low IFR scenarios (4.1% of the time). The consistent westerly wind pattern suggests runway selections will typically favor 13/31 or 14/32 configurations, with minimal wind-related approach restrictions.
