Understanding Airport Weather Reports: A Step-by-Step Guide

Last updated: 2026-06-22

When preparing for a flight, understanding the weather at your departure airport is crucial. Two primary aviation weather reports provide this information: METAR (Meteorological Aerodrome Report) and TAF (Terminal Aerodrome Forecast).

Summary

• METAR: An hourly weather observation report.
• TAF: A forecast for the next 24 to 30 hours.
• Decoding METAR: Includes wind, visibility, sky conditions, and more.
• Decoding TAF: Focuses on forecasted weather elements.

What is a METAR?

A METAR is an hourly weather observation report used in aviation. It provides current weather conditions at a specific airport, including:

• Wind: Direction and speed.
• Visibility: Distance at which objects can be seen.
• Sky Conditions: Cloud cover and type.
• Temperature and Dew Point: Air and dew point temperatures.
• Altimeter Setting: Pressure adjusted to sea level.

For example, a METAR might read:

KLIT 200953Z 00000KT 4SM -RA BR OVC030 07/05 A3013 RMK AO2 SLP205

This indicates:

• KLIT: Little Rock National Airport.
• 200953Z: Observation on the 20th at 09:53 UTC.
• 00000KT: Calm winds.
• 4SM: Visibility of 4 statute miles.
• -RA BR: Light rain and mist.
• OVC030: Overcast at 3,000 feet.
• 07/05: Temperature 7°C, dew point 5°C.
• A3013: Altimeter setting of 30.13 inches of mercury.

Decoding METAR reports can be complex, but resources like the NWS Little Rock's METAR Decoding Guide provide detailed explanations.

What is a TAF?

A TAF is a forecast for the next 24 to 30 hours, focusing on weather conditions that may affect airport operations. It includes:

• Wind: Direction and speed.
• Visibility: Forecasted distances.
• Sky Conditions: Expected cloud cover.
• Significant Weather: Forecasted precipitation or phenomena.

For instance, a TAF might state:

TAF KPIT 091730Z 0918/1024 15005KT 5SM HZ FEW020 WS010/31022KT

This indicates:

• KPIT: Pittsburgh International Airport.
• 091730Z: Forecast issued on the 9th at 17:30 UTC.
• 0918/1024: Valid from the 9th at 18:00 UTC to the 10th at 24:00 UTC.
• 15005KT: Wind from 150° at 5 knots.
• 5SM: Visibility of 5 statute miles.
• HZ: Haze.
• FEW020: Few clouds at 2,000 feet.
• WS010/31022KT: Wind shear at 1,000 feet with wind from 310° at 22 knots.

Decoding TAF reports requires understanding specific codes and formats. The Key to Aerodrome Forecast (TAF) and Aviation Routine Weather Report (METAR) provides a comprehensive guide.

How to Access METAR and TAF Data

Official METAR and TAF reports are publicly accessible and can be integrated into applications. The Aviation Digital Data Service (ADDS) provides METAR text reports and their translations.

Understanding METAR and TAF Codes

Both METAR and TAF reports use standardized codes and abbreviations. For example, BKN stands for broken clouds, and TSRA indicates thunderstorm with rain. A comprehensive list of these abbreviations can be found in the METAR Abbreviations Quick-Reference.
