Hamburg-Fuhlsbüttel · 18 February 2022 · strongest gust in each 10 minutes
The red rule is 62 km/h — wind force 8, the threshold written into standard German building-insurance conditions.
Your insurer wants proof of the storm. The instruments already have it.
Name your town and the day of the damage. You get the gusts measured at the nearest weather stations, how far away they were, and whether they reached the force your policy names — free, in about ten seconds.
Free. No account. The document costs money; finding out never does.
Questions people ask first
- Is a weather service extract enough for my insurer?
- It is the evidence the question turns on: standard German building-insurance conditions define storm as wind force 8, and a record from the national weather service shows what was measured near your address that day. It is not an expert opinion on your damage, and it does not replace the loss adjuster — it settles the part of the argument that is about the weather.
- What is wind force 8, in numbers?
- 62 kilometres an hour, measured as a gust. That is the threshold standard conditions name, and it is the line drawn across every chart on this site. Below it, a record documents a gust that will rarely help a claim, and we say so before you pay.
- Can it show hail at my address?
- For German addresses from 23 September 2026, yes. The German weather service classifies what is falling every five minutes from radar, hail included, and deletes the classification after 48 hours; this site keeps every frame. The free check says whether hail was classified over your address's own square kilometre or within 5 km, and when; where it was, the record carries those frames themselves. For earlier dates and other countries it lists the hail the nearby weather stations reported, where they report it.
- What do I get for the price?
- A dated PDF about one address and one day: the gusts measured at the nearest stations with the distance to each, the rain and hail observations, a ten-year comparison at the nearest station, and an appendix naming every archive file the figures were read from. It carries a public verification page and a content hash, so the reader can check it without trusting you.
- Do I need an account?
- No. You enter an address, a date and an e-mail. The record appears at a link of its own, which is also mailed to you, and nothing else about you is stored.
MESS_DATUMHow it works
Three steps, no opinion in any of them
You give an address and a date
The address is resolved to a coordinate and the date to a German local day, because a gust at 00:30 carries the previous day in UTC and getting that wrong changes the answer.
The archives are read
Every station within reach that actually recorded gusts, rain or present weather on that day is read straight from the national weather service's public archive — not from a copy, not from a model.
You get the record
A dated PDF with every figure, the station that produced it, the distance, the quality level and the address of the archive file it came from. Anyone can open the same file and check it.
FX_10What is in it
Everything measured, and the trail back to it
Gusts at the nearest stations
Peak gust in km/h and m/s, the Beaufort force, the minute it blew, the distance and direction from your address, and the quality level the service published with the value.
The threshold, stated plainly
Whether the measurement reached 62 km/h — wind force 8 — quoted as what the standard conditions say, never as a statement about your policy.
Rain and hail
Day totals and peak intensity from the nearest rain gauges, and any hail actually observed at a station near the address, with the observation code.
Ten years of context
Where the day ranks among every daily gust that station has recorded in the ten years before it, and how often it has been that windy.
A provenance appendix
Every dataset, publisher, licence and archive file address, printed in full, so the numbers can be checked without asking us.
A verification page
The record has a public address and a hash over its measured content. Your insurer can open it and see the same figures.
-999What it is not
The parts we will not pretend to have
Not an expert opinion
Nobody has inspected your roof, read your policy or assessed your claim. This is a data extract with its sources attached.
No lightning
There is no lightning feed in Europe that can be licensed for this at a sane price, and the community networks forbid exactly this use. So we do not report lightning at all rather than estimate it.
Hail is thinly observed
Hail is seen at points, not measured across an area, and the observing network is far coarser than a hail swath. When no station saw it, the record says so — that is not evidence that none fell.
Distance is printed, always
Across Germany the nearest station that actually records gusts is a median 11.6 km from a home. Past 25 km we will not sell you a record about your address.
