Your Guide to Understanding Airport Weather Reports

June 22, 2026 · The Clime Team

When planning air travel, understanding airport weather reports is crucial for safety and efficiency. These reports provide real-time information on conditions that can affect flight operations. In this guide, we'll explore the primary types of airport weather reports: METARs, TAFs, and ATIS broadcasts.

What Are METARs and How Do They Help?

METARs (Meteorological Aerodrome Reports) are standardized weather observations issued at airports, typically every hour. They offer a snapshot of current weather conditions, including wind speed and direction, visibility, cloud cover, temperature, dew point, and barometric pressure. Pilots and flight planners use METARs to assess whether conditions are suitable for flight and to make informed decisions about routing and altitudes.

Key Components of a METAR:

Station Identifier: A four-letter ICAO code representing the airport.
Date and Time: The day of the month and time in UTC when the observation was made.
Wind Information: Direction in degrees true and speed in knots.
Visibility: Measured in meters or statute miles.
Weather Phenomena: Codes indicating weather events like rain (RA), snow (SN), or fog (FG).
Sky Condition: Cloud cover details, including type and altitude.
Temperature and Dew Point: Measured in degrees Celsius.
Altimeter Setting: Pressure in inches of mercury.

For example, a METAR might read:

"METAR KJFK 041856Z 27015G25KT 10SM FEW040 SCT250 22/12 A3012"

This indicates that at John F. Kennedy International Airport (KJFK) on the 4th day of the month at 18:56 UTC, the wind is from 270 degrees at 15 knots with gusts up to 25 knots, visibility is 10 statute miles, there are a few clouds at 4,000 feet and scattered clouds at 25,000 feet, the temperature is 22°C, the dew point is 12°C, and the altimeter setting is 30.12 inches of mercury.

What Are TAFs and How Do They Assist in Flight Planning?

TAFs (Terminal Aerodrome Forecasts) are weather forecasts specifically tailored for the area within a 5-mile radius of an airport. They provide expected weather conditions over a 24 to 30-hour period, including forecasts for wind, visibility, cloud cover, and significant weather events. TAFs are essential for pilots to anticipate changing weather patterns and plan their flights accordingly.

Key Elements of a TAF:

Forecast Period: The time frame for the forecast, typically 24 to 30 hours.
Wind Forecast: Expected wind direction and speed.
Visibility Forecast: Anticipated visibility in meters or statute miles.
Cloud Cover Forecast: Predicted cloud types and altitudes.
Significant Weather Events: Forecasts for phenomena like rain, snow, or fog.

An example of a TAF is:

"TAF KJFK 041720Z 0418/0518 27015G25KT P6SM FEW040 SCT250"

This forecast indicates that from 18:00 UTC on the 4th to 18:00 UTC on the 5th, the wind at KJFK is expected to be from 270 degrees at 15 knots with gusts up to 25 knots, visibility will be greater than 6 statute miles, there will be a few clouds at 4,000 feet, and scattered clouds at 25,000 feet.

What Is ATIS and How Does It Benefit Pilots?

ATIS (Automatic Terminal Information Service) is a continuous broadcast of recorded aeronautical information at towered airports. It includes current weather conditions, active runways, approach information, and other operational details. Pilots listen to ATIS broadcasts before departure and upon arrival to receive the latest information without having to communicate directly with air traffic control.

Key Information Provided by ATIS:

Airport Identifier: A unique code for the airport.
Weather Information: Current conditions, including wind, visibility, and significant weather events.
Runway Information: Active runways in use.
Approach Information: Details about available approaches.
Operational Notes: Any special instructions or notices.

For instance, an ATIS broadcast might state:

"KJFK Information Alpha, 1800 Zulu, wind 270 degrees at 15 knots, gusting to 25, visibility 10 statute miles, few clouds at 4,000 feet, scattered clouds at 25,000 feet, runway 4 left in use, expect ILS approach, advise on initial contact you have information Alpha."

How Do Pilots Use These Reports Together?

Pilots integrate information from METARs, TAFs, and ATIS broadcasts to form a comprehensive understanding of current and forecasted weather conditions at their departure and arrival airports. This integration aids in making informed decisions about flight planning, including route selection, fuel requirements, and potential alternates.
