Comment 3 TraceyC 2026-05-21 17:13:55 UTC
I can reproduce what you're seeing with Plasma 6.6.5. The problem is likely due to a time zone calculation error. It's either coming from wetter.com or it's in the widget code. I saw that wetter.com, which is a German weather service, is the only provider listed for Firestone, CO

The website displays temperatures correctly for the city
https://www.wetter.com/vereinigte-staaten/firestone/US5577008.html

The Weather widget developers can take a look and see where the root cause is.

applets/weather: fix Wetter.com forecast timestamps

Wetter.com provides both UTC and local timestamps for forecasts, but the
UTC timestamp was previously converted using the system's local timezone.
This caused forecast times to be displayed in the wrong timezone.

Use the difference between the provided local and UTC timestamps to
determine the forecast timezone and preserve the weather location's local
time.
