Weather Briefing

VFR

Mehrabad International Airport is currently reporting visual flight rules (VFR) conditions with scattered clouds at 9,000 feet and 10 miles or greater visibility.

Wind Analysis

Winds are from the west (270°) at 19 knots. Runway 27 is favored with a 19-knot headwind and 0-knot crosswind component. Student pilots and low-time aviators should exercise caution.

Visibility & Ceiling

Visibility is unrestricted. No ceiling exists. Cloud layers reported: scattered at 9,000 ft.

Temperature & Moisture

Temperature is 27°C (81°F) with a dewpoint of -7°C, indicating very dry conditions. High temperatures at this elevation may result in significant density altitude effects. Pilots should calculate density altitude and adjust performance expectations accordingly.

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 Showers RA/TS, SA/DU, Light Showers Rain, Thunderstorm Rain, SA/DU. Winds are forecast to reach up to 20 knots during the period. Expect variable wind speeds ranging from 8 to 20 knots. Temporary IFR conditions are forecast with Light Showers RA/TS, SA/DU between 13:00Z and 19:00Z. Temporary VFR conditions are forecast between 23:00Z and 05:00Z. There is a 40% probability of MVFR conditions with Light Showers Rain.

Pilot Recommendations

Conditions are favorable for visual flight. 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 Mehrabad International Airport

Overview

Mehrabad International Airport serves as a primary aviation hub in Tehran, Iran, situated at an elevation of 3,962 feet above mean sea level. The airport is a large international facility with significant infrastructure, featuring three substantial runways that support diverse aircraft operations. Its strategic location in the capital city makes it a critical transportation center for both commercial and potentially military aviation activities.

Flying Conditions

Located at a considerable elevation of 3,962 ft MSL, Mehrabad experiences varied atmospheric conditions that can impact flight operations. Pilots should anticipate potential performance challenges related to the airport's higher altitude, which can affect aircraft climb rates and engine performance. The multiple runway configurations (09/27, 11L/29R, and 11R/29L) provide operational flexibility to manage different wind and weather scenarios.

Notable Features

The airport features three runways with significant length variations: a shorter 1,554 ft concrete runway (09/27), and two extensive asphalt runways measuring 11,962 ft (11L/29R) and 13,258 ft (11R/29L). These substantial runway lengths accommodate a wide range of aircraft types and provide excellent operational versatility. The geographic coordinates (35.689201, 51.313400) place the airport in the urban environment of Tehran, which introduces potential complex airspace and terrain considerations.

Approach Considerations

Runway orientation suggests potential wind-related approach considerations, with multiple runway headings offering options for different wind conditions. The longest runway (11R/29L at 13,258 ft) provides extensive landing and takeoff capabilities for heavy aircraft. Pilots should prepare for potential urban terrain effects and be ready to adapt to the airport's elevation when planning approaches and departures.
