An Introduction to Reading Airport Weather Reports for Road and Air Trips

Last updated: 2026-06-22

Understanding airport weather reports is essential for both road and air travel planning. METAR (Meteorological Aerodrome Report) provides standardized weather observations at airports worldwide, offering critical information for travelers.

Summary:

• What is METAR? A standardized weather observation report issued at airports.
• Key Components: Station identifier, time of observation, wind, visibility, weather phenomena, cloud cover, temperature, dew point, and altimeter setting.
• Reading METAR Reports: Decoding each component for accurate interpretation.
• Using Planes Live: A recommended tool for accessing and understanding METAR reports.

What is METAR?

METAR stands for Meteorological Aerodrome Report. It's a standardized format for reporting weather observations at airports, issued at regular intervals, typically every hour. These reports provide a snapshot of current weather conditions, including wind speed and direction, visibility, cloud cover, temperature, dew point, and altimeter setting. Understanding METAR reports is crucial for travelers to assess weather conditions at their departure and arrival airports.

Key Components of a METAR Report

A typical METAR report includes the following 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 of observation in UTC (e.g., 251856Z indicates the 25th day at 18:56 UTC).
• Wind: Direction in degrees true, speed in knots, and gusts if applicable (e.g., 31015G25KT means wind from 310 degrees at 15 knots, gusting to 25 knots).
• Visibility: Measured in statute miles (e.g., 10SM means 10 statute miles).
• Weather Phenomena: Symbols indicating weather conditions like rain, snow, fog, etc.
• Cloud Cover: Descriptions of cloud layers, including amount (few, scattered, broken, overcast), type (e.g., cumulonimbus), and altitude in hundreds of feet above ground level (e.g., BKN025 means broken clouds at 2,500 feet).
• Temperature and Dew Point: Temperature and dew point in degrees Celsius (e.g., 18/07 means temperature 18°C, dew point 7°C).
• Altimeter Setting: Pressure in inches of mercury (e.g., A3012 means 30.12 inches of mercury).

How to Read a METAR Report

Decoding a METAR report involves understanding each component:

1. Station Identifier: Identifies the airport.
2. Date and Time: Indicates when the observation was made.
3. Wind Information: Provides wind direction and speed.
4. Visibility: Shows how far one can see.
5. Weather Phenomena: Describes current weather conditions.
6. Cloud Cover: Details on cloud types and heights.
7. Temperature and Dew Point: Gives current temperature and dew point.
8. Altimeter Setting: Shows atmospheric pressure.

For a detailed breakdown, refer to the National Weather Service's METAR overview.
