Understanding Airport Weather Reports in 2026

In 2026, understanding airport weather reports is crucial for aviation safety and operational efficiency. Two primary reports provide this information: METAR and TAF.

What Are METAR and TAF Reports?

METAR (Meteorological Aerodrome Report) and TAF (Terminal Aerodrome Forecast) are standardized formats for reporting and forecasting weather conditions at airports.

• METAR: An hourly observation detailing current weather conditions, including wind, visibility, cloud cover, temperature, and pressure.

• TAF: A forecast predicting expected weather conditions over a 24- to 30-hour period within a 5-statute-mile radius of the airport.

How to Read a METAR Report

A METAR report consists of several key components:

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 observation date and time in UTC (e.g., 041600Z indicates the 4th day of the month at 16:00 UTC).

3. Wind Information: Direction in degrees and speed in knots (e.g., 12012MPS means wind from 120° at 12 meters per second).

4. Visibility: Horizontal visibility in meters or statute miles (e.g., 1400 meters).

5. Weather Phenomena: Current weather conditions, such as rain (RA), snow (SN), or fog (FG).

6. Cloud Cover: Cloud types and heights (e.g., BKN022 means broken clouds at 2,200 feet).

7. Temperature and Dew Point: Air and dew point temperatures in degrees Celsius (e.g., M04/M07 means -4°C and -7°C).

8. Altimeter Setting: Pressure in hectopascals (e.g., Q1020 means 1,020 hPa).

9. Remarks: Additional information, such as runway conditions or significant weather changes.

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

How to Read a TAF Report

A TAF report includes:

1. Header Line: Type, station, issue time, and validity period (e.g., TAF KJFK 251130Z 2512/2612).

2. Base Forecast: Initial expected conditions (e.g., 31012KT P6SM FEW040 BKN250).

3. Change Groups: Forecasted changes in conditions, such as:

   • FM (From): Significant change at a specific time (e.g., FM251800 27015G25KT).

   • TEMPO: Temporary conditions expected during a specific period (e.g., TEMPO 2520/2524 4SM -SHRA BKN025).

   • BECMG: Gradual change over a period (e.g., BECMG 2520/2524 4SM -SHRA BKN025).

   • PROB: Probability of occurrence (e.g., PROB30 2520/2524 4SM -SHRA BKN025).

For a comprehensive guide, see MetarCentral's TAF guide.

Why Are METAR and TAF Reports Important?

These reports are essential for:

• Flight Planning: Determining suitable weather conditions for departure and arrival.

• Safety: Identifying hazardous weather phenomena that may affect flight operations.

• Operational Efficiency: Optimizing flight routes and schedules based on forecasted conditions.
