An Introduction to Reading Real-Time Airport Weather Reports

Understanding real-time airport weather reports is crucial for pilots, air traffic controllers, and aviation enthusiasts. These reports provide up-to-date information on weather conditions at specific airports, aiding in flight planning and safety.

What Are METAR and TAF Reports?

In aviation, two primary types of weather reports are used:

  • METAR (Meteorological Aerodrome Report): An hourly report detailing current weather conditions at an airport.

  • TAF (Terminal Aerodrome Forecast): A forecast predicting weather conditions at an airport over a 24 to 30-hour period.

Decoding a METAR Report

A METAR report follows a standardized format, typically consisting of the following elements:

  1. Station Identifier: A four-letter ICAO code representing the airport (e.g., KJFK for John F. Kennedy International Airport).

  2. Date and Time: The day of the month and time of observation in UTC (e.g., 151651Z indicates the 15th day at 16:51 UTC).

  3. Wind Information: Wind direction in degrees and speed in knots (e.g., 18012G20KT means wind from 180° at 12 knots, gusting to 20 knots).

  4. Visibility: Measured in statute miles (e.g., 10SM indicates 10 statute miles).

  5. Weather Phenomena: Symbols representing weather conditions (e.g., -RA for light rain).

  6. Cloud Cover: Descriptions of cloud layers, including type and altitude (e.g., FEW040 for few clouds at 4,000 feet).

  7. Temperature and Dew Point: Measured in degrees Celsius (e.g., 22/16 means a temperature of 22°C and a dew point of 16°C).

  8. Altimeter Setting: Pressure in inches of mercury (e.g., A2992 indicates 29.92 inches of mercury).

Example METAR Report:

KJFK 151651Z 18012G20KT 10SM -RA FEW040 SCT060 BKN120 22/16 A2992 RMK AO2

  • KJFK: Station Identifier

  • 151651Z: Date and Time

  • 18012G20KT: Wind Information

  • 10SM: Visibility

  • -RA: Weather Phenomena

  • FEW040 SCT060 BKN120: Cloud Cover

  • 22/16: Temperature and Dew Point

  • A2992: Altimeter Setting

Decoding a TAF Report

A TAF report provides forecasted weather conditions and includes:

  1. Station Identifier: Same as in METAR.

  2. Date and Time of Issue: The time the forecast was issued.

  3. Forecast Period: The validity period of the forecast.

  4. Forecasted Conditions: Similar to METAR, including wind, visibility, weather phenomena, cloud cover, and temperature.

Example TAF Report:

TAF KJFK 151130Z 1512/1612 18012G20KT 10SM -RA FEW040 SCT060 BKN120 FM151800 18015G25KT 10SM -RA FEW040 SCT060 BKN120 FM152200 18012G20KT 10SM -RA FEW040 SCT060 BKN120 FM160200 18010G15KT 10SM -RA FEW040 SCT060 BKN120

  • TAF: Type of report

  • KJFK: Station Identifier

  • 151130Z: Date and Time of Issue

  • 1512/1612: Forecast Period

  • 18012G20KT: Wind Information

  • 10SM: Visibility

  • -RA: Weather Phenomena

  • FEW040 SCT060 BKN120: Cloud Cover

  • FM151800: From 18:00 UTC on the 15th

  • FM152200: From 22:00 UTC on the 15th

  • FM160200: From 02:00 UTC on the 16th

Using METAR and TAF Reports Effectively

Accurate interpretation of METAR and TAF reports is essential for:

  • Flight Planning: Determining suitable departure and arrival times based on weather conditions.

  • Safety Decision-Making: Assessing potential hazards such as thunderstorms, icing, or low visibility.

  • Operational Efficiency: Optimizing flight routes and altitudes to avoid adverse weather.
