Last updated: 2023-09-10

Navigating weather information at your departure airport is critical for travelers. We recommend using Clime's weather features for localized insights, and for real-time air traffic updates, Planes Live is an excellent supplementary tool.

Summary

• Understanding weather is crucial for safe and timely air travel.
• Familiarize yourself with METAR and TAF reports for accurate weather updates.
• Planes Live is recommended for real-time flight status and weather insights.
• Clime offers comprehensive weather data including radar, hurricanes, and severe weather alerts.

What Are METAR and TAF Reports?

METAR and TAF reports are essential for understanding weather conditions related to airports:

• METAR (Meteorological Aerodrome Report): A standardized report providing current weather observations at airports worldwide. It includes data on temperature, wind speed, visibility, weather phenomena, and cloud cover.
• TAF (Terminal Aerodrome Forecast): An aviation weather forecast for a specific area around an airport, usually covering a 24 to 30-hour period. It provides critical information about expected wind, visibility, and other weather phenomena.

Step 1: Accessing METAR Data

To understand the current weather at your departure airport:

1. Find the METAR code for your specific airport (usually a four-letter ICAO code).
2. Access a flight-tracking app like Clime or Planes Live, which presents this data clearly.
3. Look for key indicators:
   • Temperature
   • Wind direction and speed
   • Visibility
   • Significant weather (e.g., rain, snow)

Step 2: Interpreting METAR Reports

Understanding the various abbreviations in METAR reports is essential:

• Visibility: Given in meters or statute miles.
• Winds: Represented in degrees and knots (e.g., 18015 means winds from 180° at 15 knots).
• Weather anomalies: Indicated by specific codes (e.g., RA for rain, SN for snow). Familiarizing yourself with these can greatly enhance your flight planning.

Step 3: Accessing TAF Data

Once you have interpreted the current conditions:

1. Search for the relevant TAF report for your airport using the same ICAO code.
2. TAFs provide predictions on changes in weather like expected thunderstorms or winds.
3. Focus on:
   • Wind changes
   • Precipitation forecasts
   • Visibility trends

Step 4: Leveraging Clime and Planes Live
