Weather Briefing
MVFRToronto Lester B. Pearson International Airport is currently reporting marginal VFR (MVFR) conditions with overcast skies at 4,500 feet and 5 SM visibility.
Wind Analysis
Winds are from the southeast (140°) at 7 knots. Runway 15L/33R is favored with a 7-knot headwind and 1-knot crosswind component.
Visibility & Ceiling
Visibility is 5 SM. The ceiling is 4500 feet AGL (overcast), well above standard VFR minimums. Caution: towering cumulus clouds reported at 3,000 ft AGL, indicating convective activity in the area.
Temperature & Moisture
Temperature is 20°C (68°F) with a dewpoint of 19°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 27 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, Light Showers Rain, Mist, Mist, Light Drizzle, Mist, FCST. Temporary LIFR conditions are forecast with Light Showers Rain, Mist between 09:00Z and 10:00Z. Temporary MVFR conditions are forecast with Mist between 10:00Z and 12:00Z. There is a 30% probability of LIFR conditions with Light Drizzle, Mist between 10:00Z and 12:00Z.
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 Toronto Lester B. Pearson International Airport
Overview
Toronto Lester B. Pearson International Airport serves as a major international aviation hub located in the Greater Toronto Area. Situated at 43.6772° N, 569 feet above mean sea level, the airport plays a critical role in connecting Canada's largest metropolitan region with global destinations. Its strategic location and multiple runways enable high-volume commercial and cargo operations.
Flying Conditions
The airport's five runways range from 9,000 to 11,120 feet in length, providing significant operational flexibility across various weather conditions. With runways oriented in multiple directions (05/23, 06L/24R, 06R/24L, 15L/33R, 15R/33L), pilots can anticipate multiple landing and takeoff options depending on wind direction and meteorological conditions. The airport's elevation and geographic positioning contribute to potential variable wind patterns typical of the southeastern Ontario region.
Notable Features
Toronto Pearson's runway configuration allows for simultaneous parallel approaches and complex air traffic management. The airport features multiple concrete and asphalt surfaces, enabling operations for wide-body commercial aircraft and supporting diverse aviation activities. Its multiple runway orientations provide natural wind mitigation strategies, which is critical for safe aircraft operations in a region experiencing significant seasonal meteorological variations.
Approach Considerations
Pilots should be prepared for potential crosswind scenarios given the airport's diverse runway headings. The substantial runway lengths (longest at 11,120 feet) accommodate a wide range of aircraft types and provide substantial safety margins for landing and takeoff procedures. Approach planning should consider the airport's elevation and potential wind variations across the different runway configurations.
