Weather translator

METAR & TAF Weather

Review observed and forecast weather in Navigator’s scrolling timeline, translate coded observations, and search the complete aviation contraction reference preserved from the original CFIBastian site.

METAR / SPECI

Airport weather

METAR + TAF
Enter an ICAO identifier and fetch weather when you need it. Nothing loads automatically. Some airports do not issue a TAF. Location is requested only when you click and is not stored.
Paste or inspect raw METAR / SPECI

Pasted reports are decoded locally. Their date and freshness are not verified.

Operational reminder

This translator is a study and planning aid. Always review the complete raw report and obtain current official weather information for flight decisions.

The decoder supports METAR/SPECI body groups, common U.S. remarks, and international visibility/QNH formats. Unrecognized groups remain visible for verification. Forecast intervals use the same decoding logic as Navigator. Conditional changes remain separate from prevailing conditions. Always check the original TAF for unsupported groups.
