Weather Briefing

MVFR

Toronto Lester B. Pearson International Airport is currently reporting marginal VFR (MVFR) conditions with overcast skies at 2,100 feet and 15 SM visibility.

Wind Analysis

Winds are from the north-northwest (340°) at 14 knots. Runway 33 is favored with a 14-knot headwind and 2-knot crosswind component.

Visibility & Ceiling

Visibility is 15 SM. The ceiling is 1400 feet AGL (broken), placing conditions in the MVFR category.

Temperature & Moisture

Temperature is 8°C (46°F) with a dewpoint of 5°C. The narrow temperature-dewpoint spread suggests high humidity and potential for visibility restrictions, especially during cooling periods.

Forecast Outlook

The TAF forecast covers the next 30 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 Drizzle, Light Rain, FCST. Expect variable wind speeds ranging from 3 to 15 knots. Temporary VFR conditions are forecast between 12:00Z and 14:00Z. There is a 40% probability of IFR conditions between 12:00Z and 14:00Z. Temporary MVFR conditions are forecast with Light Rain between 14:00Z and 23:00Z.

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.

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

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.
