Weather Briefing

VFR

Calgary International Airport is currently reporting visual flight rules (VFR) conditions with broken clouds at 7,800 feet and 10 SM visibility.

Wind Analysis

Winds are from the northwest (320°) at 8 knots. Runway 29 is favored with a 7-knot headwind and 4-knot crosswind component.

Visibility & Ceiling

Visibility is 10 SM. The ceiling is 7800 feet AGL (broken), well above standard VFR minimums.

Temperature & Moisture

Temperature is 10°C (50°F) with a dewpoint of 7°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 21 hours. Conditions are expected to fluctuate between VFR and MVFR. VFR pilots should be prepared for deteriorating conditions. Expected weather includes: Showers Rain, Mist, Light Rain, Light Rain, Mist, Light Showers Rain, Thunderstorm Rain, Light Showers Rain, FCST. Temporary VFR conditions are forecast with Showers Rain, Mist between 09:00Z and 14:00Z. Temporary MVFR conditions are forecast with Light Rain, Mist between 14:00Z and 20:00Z. Temporary VFR conditions are forecast with Light Showers Rain between 20:00Z 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 Calgary International Airport

Overview

Calgary International Airport serves as a major aviation hub in western Canada, located in Alberta approximately 12 kilometers northeast of downtown Calgary. As a large international airport with significant infrastructure, CYYC handles diverse commercial, cargo, and general aviation traffic. The airport's substantial elevation of 3,557 feet mean sea level impacts aircraft performance and operational considerations.

Flying Conditions

Calgary's airport experiences significant seasonal variability typical of prairie region climate, with potential for rapid weather transitions. Winter conditions can produce challenging crosswind and low visibility scenarios, especially given the airport's multi-runway configuration. The comprehensive runway system (four runways ranging from 6,200 to 14,000 feet) provides operational flexibility across different meteorological conditions.

Notable Features

The airport's geographical positioning in Alberta's foothills region introduces complex terrain interactions that can affect local wind patterns and turbulence. With runways oriented in multiple directions (08/26, 11/29, 17L/35R, 17R/35L), pilots have strategic options for approaches based on current wind vectors. The longest concrete runway (17L/35R at 14,000 feet) provides exceptional landing and takeoff capabilities for heavy aircraft.

Approach Considerations

Pilots should anticipate potential wind shear and turbulence due to the airport's elevation and surrounding topographical features. Runway selection will primarily depend on wind direction, with the 14,000-foot concrete runway (17L/35R) offering the most comprehensive operational parameters. The multiple runway orientations allow for adaptive approach strategies across different wind conditions.
