Implementation notes

When to use Bright Sky (DWD)

Bright Sky is the right pick for any project focused on German weather. It wraps the Deutscher Wetterdienst (DWD) open data feeds — the same source the German weather service itself uses — with a clean JSON API. Coverage is exclusively Germany with high station density; outside Germany it returns nothing.

Common pitfalls

No key, no rate limit documented — but the maintainer asks heavy users to self-host the open-source Bright Sky instance against the DWD data directly. Public endpoint courtesy use only.
Returns null for fields where DWD has no station data. Rural locations far from a station will show many null fields, which trips up code that assumes a number is always returned.
The `current_weather` endpoint requires coordinates (lat, lon). City name lookup is not built in — pair with Nominatim or a coordinate lookup before the call.

Quick start (bash)
