Understanding aviation weather reports is essential for safe flight planning. This guide will help you decode METAR and TAF reports quickly and confidently.
What is a METAR?
METAR (Meteorological Aerodrome Report) is an observation of current weather conditions at an airport. METARs are typically issued hourly, with special reports (SPECI) issued when conditions change significantly.
FM (From) - Rapid change expected at specified time
TEMPO - Temporary fluctuations (less than half the period)
BECMG - Gradual change expected
PROB - Probability of conditions (PROB30, PROB40)
VFR Weather Minimums
Class G Airspace (Day):
1 statute mile visibility
Clear of clouds
Class E, D, C, B Airspace:
3 statute miles visibility
500' below, 1000' above, 2000' horizontal from clouds
Making Go/No-Go Decisions
Use weather reports to evaluate:
Is visibility above your personal minimums?
Are ceilings high enough for your planned altitude?
Are winds within your crosswind limits?
Is the trend improving or deteriorating?
Do you have alternates if conditions change?

Finally understand what all those abbreviations mean! The table breaking down cloud coverage codes is super helpful. Bookmarked this for quick reference.
