German Weather Warnings – Official DWD Alerts (CAP)

Get all current official weather warnings for Germany as structured data, straight from the Deutscher Wetterdienst (DWD), Germany's national meteorological service. Thunderstorms, storm gusts, heavy rain, snow, black ice, frost, heat, UV and fog. The warnings come per district or municipality. Each row is one warning for one area. It includes:

• event (e.g. STURMBÖEN, SCHWERES GEWITTER, GLÄTTE) and event group (WIND, THUNDERSTORM, ICE …)
• severity on the DWD scale: Minor (yellow), Moderate (orange), Severe (red), Extreme (violet)
• start (onset), end (expires) and when the warning was issued (sent)
• headline, description and the DWD's instructions
• altitude range in metres (e.g. snow only above 800 m)
• area name, warn cell ID, official district key (AGS) and state
• measured or expected values, e.g. gusts in km/h or visibility in m
• warning texts in German, English or Spanish

Ask by area name, state, event type or severity. You can also ask whether a point (latitude, longitude) lies inside a warning area.

For AI agents: call this Actor when a user asks "Is there a storm warning for Munich right now?", "Which districts have a heat warning today?", "Are there severe thunderstorm warnings in Bavaria?" or "Is my location 50.94, 6.96 affected by a weather warning?". Pass areas, near, states, eventGroups, minSeverity or onlyActiveNow. Set language: "en" for English texts.

Price: $1 per 1,000 rows ($0.001 per result). If no warning is active, nothing is charged except the tiny start fee.

Use cases

• Logistics, construction and event planning: check routes, sites and venues for storm, ice or thunderstorm warnings.
• Insurers and facility managers: log warnings per district for claims handling and prevention.
• Apps, smart home and alerting: schedule the Actor (e.g. every 15 minutes) and send your own notifications.
• AI assistants: answer "is there a weather warning here?" with the official source.

Input examples

Storm and thunderstorm warnings (orange or higher) active now in Bavaria, in English:

{ "states": ["BY"], "eventGroups": ["WIND", "THUNDERSTORM"], "minSeverity": "Moderate", "onlyActiveNow": true, "language": "en" }

Is there any warning at a location?

{ "near": "50.94, 6.96" }

All warnings for some cities and districts:

{ "areas": ["München", "Köln", "Region Hannover"] }

Reliability and fair use

• One request per run: the DWD's official "latest status" file with all valid warnings (updated several times per hour).
• Every warning file is checked for the CAP structure. Every row is validated: ID, event, severity, headline, area and ISO times. If the format changes, the run fails with UNEXPECTED_CONTENT. Invalid rows are dropped and not charged.
• An empty status file means: no warnings are active right now. That is a normal result, not an error.
• Cancelled warnings and test messages are skipped. The most severe warnings come first.

Legal

• Source: Deutscher Wetterdienst (DWD), opendata.dwd.de. Reuse is allowed under CC BY 4.0 with the attribution "Deutscher Wetterdienst". Every row carries it.
• Area outlines (optional) are based on © GeoBasis-DE / BKG (data modified). This attribution is added to rows with polygons.
• Only the warnings on dwd.de and in the DWD's WarnWetter app are authoritative. This Actor is not affiliated with the DWD.
