German Weather Warnings (DWD) – Storm, Snow, Ice

Get the official weather warnings for Germany from the Deutscher Wetterdienst (DWD), the national weather service – the same warnings shown in the WarnWetter app and on dwd.de, as clean JSON, CSV or Excel.

Storm, thunderstorm, heavy rain, hail, snow, black ice, frost, fog, heat, UV and more, for every municipality in Germany, with severity level 1–4, start and end time, description and safety instructions – in English or German.

Filter by severity, type of weather, federal state, town name, or exact coordinates ("is my warehouse inside a warning area?"). No API key, no scraping, no login.

What can I use it for?

• 🚚 Logistics & fleets – check depots, routes and delivery areas for storm, snow and ice warnings every morning.
• 🏗️ Construction, events & facility management – crane and roof work, open-air events, winter road service.
• 🛡️ Insurance & risk – log which locations were under a severe weather warning, and when.
• 📱 Apps, websites & smart home – show warnings for your users' towns; trigger alerts when level 3 (Unwetter) is reached.
• 🤖 AI agents – call it as a tool via the Apify MCP server: "Are there any storm warnings for Hamburg right now?"

Run it on a schedule (e.g. every 30 minutes) with your locations to get a monitoring feed.

Data you get

One row per warning (or per warning and municipality):

Field	Meaning
event, eventGroup, eventCode	Kind of weather, e.g. "gale-force gusts" / WIND / DWD code 52
severity, level, levelName	Minor/Moderate/Severe/Extreme = DWD level 1–4
headline, description, instruction	Official texts in English or German
onset, expires, onsetUtc, expiresUtc	When the warning applies (German local time and UTC)
isPreliminary	true for advance information (Vorabinformation) before a possible severe weather warning
states, areas, areaCount, warnCellIds	Affected federal states and municipalities (with DWD warn cell ids)
isCoastal	true for coast and sea warnings (e.g. "Helgoland", "Elbe von Hamburg bis Cuxhaven"). These have no polygon and no state, so find them with place or warnCellIds rather than coordinates
parameters	Measured/expected values, e.g. gust speed, rain amount, visibility
altitudeFromM, altitudeToM	Height band, when the warning only applies above/below a height
distanceKm	0 if your point is inside the warning area, otherwise the distance (with a radius)
geometry	Warning area as GeoJSON MultiPolygon (optional)
color, id, sent, msgType	DWD map colour, warning id, issue time, Alert/Update

In per-municipality mode each row has area, warnCellId and state instead of the lists.

A summary (number of matching and active warnings, highest level, counts by severity, type and state) is saved in the key-value store under OUTPUT.

Notes

• Data is the DWD's current warning status, updated by the DWD every few minutes. Each run downloads it once.
• When there are no warnings matching your filters, the run returns no rows – you are not charged for results then.
• Coverage is Germany only. Coastal and lake (marine) warnings are not included.

Pricing

You pay only per warning row returned – no monthly fee.
