Definition#
SPECI is a Special METAR — an aviation weather observation report issued outside the normal hourly schedule when significant changes in weather conditions occur at an aerodrome.
Why It Matters Operationally#
SPECI reports ensure that rapidly changing conditions — such as visibility dropping below minimums, wind shifts, or thunderstorm onset — are communicated before the next scheduled METAR. They are critical for approach and departure decisions.
