Metar is a Python package designed to parse METAR-coded weather reports, providing easy access to various meteorological data points such as wind, temperature, visibility, and cloud conditions. The project recently settled on the package name `metar` (previously `python-metar`). It is currently at version 2.0.1, with an active release cadence, and requires Python >=3.10.

Metar

✓ from metar.Metar import Metar

✗ from python_metar.Metar import Metar

The package was historically known as `python-metar`. Ensure you use `metar` for imports with recent versions.

Parse a sample METAR string and access its attributes, then print a human-readable summary.

from metar.Metar import Metar # Example METAR string metar_string = "METAR KSLK 200853Z AUTO 09006KT 10SM CLR 02/M01 A2999 RMK AO2" # Parse the METAR report m = Metar(metar_string) # Access parsed data print(f"Station: {m.station_id}") print(f"Time: {m.time}") print(f"Wind: {m.wind_dir}{m.wind_speed}KT") print(f"Temperature: {m.temp}°C") print(f"Dew Point: {m.dewpt}°C") print(f"Visibility: {m.vis.value}{m.vis.units}") # Print a formatted report print("\n--- Formatted Report ---") print(m.string())

Debug

Known issues

breakingThe `utcdelta` argument was removed from the `Metar` constructor in version 2.0.0. This was a breaking change.

fix

Remove the `utcdelta` argument when instantiating `Metar`. The library now handles UTC offsets internally or expects UTC input.

affects: >=2.0.0

breakingThe `position.getdistance` API was removed in version 1.9.0 as it was unused and broken.

fix

If you were using `position.getdistance`, you will need to implement custom distance calculation or find an alternative method. The library no longer provides this functionality.

affects: >=1.9.0

gotchaThe package name has officially settled on `metar`. While older versions might have been installed as `python-metar`, ensure your `pip install` command and `import` statements use `metar`.

fix

Use `pip install metar` for installation and `from metar.Metar import Metar` for imports.

affects: All versions, especially when upgrading from legacy setups.

gotchaThe library now officially requires Python 3.10 or newer. Installing on older Python versions will likely result in compatibility errors.

fix

Ensure your environment uses Python 3.10 or a newer version.

affects: >=2.0.0

Errors

Common errors & fixes

ModuleNotFoundError: No module named 'python_metar'

Attempting to import using the old package name after installing the new `metar` package, or not having the `metar` package installed.

fix

Ensure you have installed the correct package with `pip install metar` and update your import statements to `from metar.Metar import Metar`.

TypeError: Metar() got an unexpected keyword argument 'utcdelta'

You are passing the `utcdelta` argument to the `Metar` constructor, which was removed in version 2.0.0.

fix

Remove the `utcdelta` argument from the `Metar` constructor call. The library no longer uses this parameter.

AttributeError: 'Position' object has no attribute 'getdistance'

You are attempting to call the `getdistance` method on a `Position` object, which was removed in version 1.9.0.

fix

This method is no longer available. You will need to implement a custom distance calculation if this functionality is required.
