python-weather fails at 12:48

Thursday, September 17, 2026

Version 2.2.5 of python-weather fails at 12:48 when locale is “fr”.

Version 2.2.5 switched from datetime.strptime to babel.dates.parse_time for parsing values in timestamp fields.

For example the observation_time field is such a field. It seems that the wttr.in service reports times between 12:00 and 13:00 differently depending on the specified locale. Anyway today in the early aftgernoon, at 12:48, my python_weather.Client (locale was python_weather.Locale(‘fr’)) received the following observation time:

>>> observation_time = "12:48 PM"

As far as I understand things, this is indeed an invalid time specification. It should be “00:48 PM”. This might be a bug in the wttr.in service.

It’s interesting that parse_time() refuses it only when locale=”en_US”.

>>> from datetime import datetime
>>> from babel.dates import parse_time

>>> parse_time(observation_time)
datetime.time(12, 48)

>>> datetime.strptime(observation_time, '%I:%M %p').time()
datetime.time(12, 48)

>>> parse_time(observation_time, locale="en_US")
Traceback (most recent call last):
  File "<doctest weather.rst[17]>", line 1, in <module>
  File "/home/luc/venvs/dev/lib/python3.14/site-packages/babel/dates.py", line 1398, in parse_time
    return datetime.time(hour, minute, second)
           ~~~~~~~~~~~~~^^^^^^^^^^^^^^^^^^^^^^
ValueError: hour must be in 0..23, not 24

I’m not sure how I would fix this.

A workaround is to not specify any locale to the weather client.
