Weather Briefing
MVFRSudbury Airport is currently reporting marginal VFR (MVFR) conditions with overcast skies at 4,200 feet and 10 SM visibility.
Wind Analysis
Winds are from the northeast (40°) at 6 knots. Runway 04/22 is favored with a 6-knot headwind and 0-knot crosswind component.
Visibility & Ceiling
Visibility is 10 SM. The ceiling is 1800 feet AGL (broken), placing conditions in the MVFR category.
Temperature & Moisture
Temperature is 20°C (68°F) with a dewpoint of 20°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. 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 Showers Rain, Mist, Light Showers Rain, Light Rain, FCST. Temporary VFR conditions are forecast with Light Showers Rain, Mist between 02:00Z and 04:00Z. Temporary MVFR conditions are forecast with Light Showers Rain, Mist between 04:00Z and 08:00Z. Temporary MVFR conditions are forecast with Light Rain, FCST between 08:00Z and 14:00Z.
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 Sudbury Airport
Overview
Sudbury Airport serves the Greater Sudbury region in Ontario, Canada, functioning as a medium-sized airport critical for regional transportation and aviation activities. Located at 46.625000, -80.798897 with an elevation of 1141 ft MSL, the airport provides essential aviation infrastructure for northeastern Ontario. Its two asphalt runways support diverse aviation operations in this northern Canadian environment.
Flying Conditions
Weather at Sudbury Airport demonstrates significant variability, with visual flight rules (VFR) conditions prevailing 56.6% of the time. Temperature ranges from -30°C to 27°C, creating challenging seasonal transitions, while wind patterns predominantly originate from the northwest at an average of 8.6 knots. September, October, and January offer the most consistent VFR conditions, with average visibility around 13.9 statute miles and occasional fog occurrence at 6.1% of observations.
Notable Features
The airport features two parallel runways: 04/22 measuring 6600 feet and 12/30 measuring 5000 feet, both constructed with asphalt surfaces. Both runways demonstrate 100% favorable wind alignment, with modest average crosswind components of 5.6 and 5.5 knots respectively. The airport's elevation and geographic location in northern Ontario suggest potential for challenging winter flying conditions.
Approach Considerations
Prevailing northwest winds at 315 degrees suggest runway 04/22 and 12/30 will generally provide favorable approach conditions. Pilots should anticipate potential reduced visibility scenarios, with 11.8% IFR and 9.4% low IFR conditions recorded. Wind speeds reaching maximum of 31 knots indicate potential turbulence, particularly during transitional seasons, requiring heightened situational awareness during arrivals and departures.
