It's been a busy late Jan/early Feb with coding to add two more sources for international, multilingual forecasts:
OpenWeatherMap (
https://openweathermap.org) and VisualCrossing (
https://visualcrossing.com). Both provide limited-use free API keys available.
Both providers only give one daily icon per-day for their forecasts, (so no day/night displays).
OpenWeatherMap does provide full translations for forecast text.
VisualCrossing provides de (German), en (English), es (Spanish), fi (Finnish), fr (French), it (Italian), pt (Portuguese), ru (Russian), nl (Netherlands), sr (Serbian). Other languages will return in English.
The OpenWeatherMap script page is
here and on GitHub

The scripts are included in the Base-World template using the
update tool with query Base-World,*.Plugin, 07-Feb-2023
Note that Base-* templates also get updated ajax-dashboard.php V1.33, wxforecast.php V1.06 and check-fetch-times.php V1.49 to support the new scripts.
For a DarkSky replacement, I'd suggest using the OpenWeatherMap one as it has the most complete translations for multilingual use.
