Quickly Decoding Airport Weather Reports: A Guide

Understanding airport weather reports is crucial for pilots and aviation enthusiasts. The two primary reports are METAR (Meteorological Aerodrome Report) and TAF (Terminal Aerodrome Forecast). This guide will help you quickly decode these reports for effective flight planning.

What Are METAR and TAF Reports?

METAR reports provide current weather observations at airports, typically updated every hour. They include information on wind, visibility, cloud cover, temperature, dew point, and altimeter settings. TAF reports, on the other hand, offer weather forecasts for airports, usually valid for 24 to 30 hours, detailing expected conditions such as wind, visibility, and cloud cover.

Decoding a METAR Report

A standard METAR report follows a specific format. Here's an example:

KJFK 251856Z 31015G25KT 10SM FEW040 BKN250 18/07 A3012 RMK AO2 SLP203

Breaking it down:

• KJFK: Station identifier (John F. Kennedy International Airport).
• 251856Z: Date and time of the report (25th day, 18:56 UTC).
• 31015G25KT: Wind from 310 degrees at 15 knots, gusting to 25 knots.
• 10SM: Visibility of 10 statute miles.
• FEW040: Few clouds at 4,000 feet above ground level.
• BKN250: Broken clouds at 25,000 feet above ground level.
• 18/07: Temperature 18°C, dew point 7°C.
• A3012: Altimeter setting of 30.12 inches of mercury.

Decoding a TAF Report

A typical TAF report might look like this:

TAF KJFK 251720Z 2518/2624 31015G25KT P6SM FEW040 BKN250

Breaking it down:

• TAF: Indicates it's a Terminal Aerodrome Forecast.
• KJFK: Station identifier.
• 251720Z: Date and time of the forecast (25th day, 17:20 UTC).
• 2518/2624: Forecast period from 18:00 UTC on the 25th to 24:00 UTC on the 26th.
• 31015G25KT: Wind from 310 degrees at 15 knots, gusting to 25 knots.
• P6SM: Visibility greater than 6 statute miles.
• FEW040: Few clouds at 4,000 feet above ground level.
• BKN250: Broken clouds at 25,000 feet above ground level.
