EventWache
A weather-aware outdoor event planner for German wedding planners, festival organizers, market vendors, and Sportverein captains — pick your date and outdoor location, and it sends tiered risk alerts (green/yellow/orange/red) with suggested backup plans and a draft Mitteilung an die Gäste.
German small-business event organizers and Vereinsvorstände running outdoor events
- Date + outdoor-location picker that pulls historical severe-weather patterns and a forecast cone
- Tiered risk alerts (Sturmwarnung, Starkregen, Hagel ≥2cm) with thresholds matching DWD definitions
- Auto-generated cancellation/postponement message templates in German and English
- Post-event weather archive with timestamps and a one-page summary for insurance claims
The Niedersachsen hailstorm and the NDR article's recurring Vereins/Sport-event advice show that small organizers repeatedly lose money to bad-weather decisions — most still rely on a 6-hour glance at the standard weather app.
Outdoor event weather risk is documented (Tagesschau on festival weather risk), and DWD WarnWetter-App has been the dominant consumer choice for years, but there's no evidence small Vereine/Hochzeitsplaner actively seek a specialized planner beyond the free DWD app.Wie Extremwetter zum Risiko für Festivals wird | tagesschau.de ↗WarnWetter-App ↗
Direct competitors exist: DWD WarnWetter-App (free, official, very high quality), MeteoFocus/Wettermanufaktur (premium B2B with personal meteorologists for large events), plus general apps like Wetter.com — no obvious white space for a small-event-specific planner, though backup-plan + Mitteilung feature is novel.Wetterbeobachtung für Events, Festivals & Sportveranstaltungen - MeteoFocus ↗Deutscher Wetterdienst - Veranstalter ↗
DWD anchors the market at a one-time €2.49 for full features, and MeteoFocus serves large events B2B; small Vereine and Marktbeschicker are notoriously price-sensitive, making recurring subscription for a weather-alert tier hard to justify when free DWD push alerts already exist.FAQ zur WarnWetter-App - Wo kann ich die Vollversion kaufen ↗Wetterbeobachtung für Events, Festivals & Sportveranstaltungen - MeteoFocus ↗
Recurring NDR/regional coverage of weather-event advice and growing extreme-weather frequency in Germany (hailstorms, Starkregen) keep this relevant; German Vereins- and Volksfest culture is deeply entrenched, so outdoor events won't disappear.Open Air 2026 — Wetter-Absicherung und Notfallplan - Event.com.de ↗Wie Extremwetter zum Risiko für Festivals wird | tagesschau.de ↗
DWD offers free OpenData APIs (Mascot/Mosmix) and the Mitteilung/BACKUP-PLAN layer is a tractable LLM feature, but the high quality bar set by the official DWD app and the liability of weather-driven decisions for events raise complexity; small German Vereinsvorstände also expect Vereins-specific tone in generated messages.Deutscher Wetterdienst - Amtliche Unwetterwarnungen ↗Unwetterwarnung zur Hochzeit - Hochzeit-Prepper ↗
