The storm of 25 December 2009 — what the instruments recorded

Questions people ask first

Was this storm strong enough to count for an insurance claim?

Standard German conditions name wind force 8 — 62 km/h as a gust. The table on this page lists what each station recorded that day; if the stations near your address reached it, the measurement supports your claim. The check on your own address answers it exactly.

How do I prove the storm reached MY street?

By naming the station, its distance and what it measured — which is what a record about your address does. Stations are a median 11.6 km apart across Germany, so the nearest one is usually close enough to be evidence; past 25 km we refuse to sell a record rather than stretch it.

Where do these numbers come from?

The national weather service's own open archive. Every figure on this page comes from a station file published by the Deutscher Wetterdienst, and the paid record prints the archive file's address next to each number.
