Decoding Airport Weather Reports: A Simple Guide

Understanding airport weather reports is essential for pilots, aviation enthusiasts, and travelers. These reports provide critical information about current and forecasted conditions at airports, ensuring safety and informed decision-making.
What Are METAR and TAF Reports?
Airport weather reports primarily consist of two types:
-
METAR (Meteorological Aerodrome Report): An hourly observation 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 typical METAR report includes several key elements:
-
Station Identifier: A four-letter ICAO code representing the airport (e.g., KJFK for John F. Kennedy International Airport).
-
Date and Time: The day of the month and time in UTC (e.g., 121551Z means the 12th day at 15:51 UTC).
-
Wind Information: Direction and speed, including gusts (e.g., 33015G25KT means wind from 330 degrees at 15 knots, gusting to 25 knots).
-
Visibility: Measured in statute miles (e.g., 10SM indicates 10 statute miles of visibility).
-
Weather Phenomena: Symbols indicating weather conditions (e.g., -RA for light rain).
-
Cloud Cover: Descriptions of cloud layers, including type and altitude (e.g., SCT030 BKN045 means scattered clouds at 3,000 feet and broken clouds at 4,500 feet).
-
Temperature and Dew Point: Given in degrees Celsius (e.g., 12/08 means a temperature of 12°C and a dew point of 8°C).
-
Altimeter Setting: Pressure in inches of mercury (e.g., A2992 means 29.92 inches of mercury).
Decoding a TAF Report
A typical TAF report includes:
-
Type of Report: Indicates whether it's a routine forecast (TAF) or an amended forecast (TAF AMD).
-
Station Identifier: Same as in METAR reports.
-
Date and Time of Origin: The date and time the forecast was issued in UTC.
-
Valid Period: The start and end times of the forecast.
-
Forecast Elements: Similar to METAR, including wind, visibility, weather phenomena, and cloud cover, but presented as forecasts over time.
