Frequently Asked Questions
What aviation weather tools are available?
BabyRain.org offers free tools including a METAR Decoder that breaks down any METAR into plain English, a comprehensive METAR Code Reference covering 60+ weather codes, and a METAR Remarks Reference for decoding the remarks section of weather observations.
How do I decode a METAR?
Use our METAR Decoder tool — paste any raw METAR string and get an instant plain-English breakdown of every element: station ID, time, wind, visibility, weather phenomena, cloud layers, temperature, dewpoint, and altimeter setting. Each field is color-coded and annotated.
What does BR mean in a METAR?
BR stands for "mist" in METAR weather codes (from the French "brume"). It indicates visibility between 5/8 and 6 statute miles due to water droplets suspended in the air. Pilots sometimes call it "baby rain" — which is where our site name comes from!
Are these tools free to use?
Yes, all tools on BabyRain.org are completely free with no sign-up required. Just open the tool and start using it.
