When it fills in
No thermal cycle to time. Wind arrives with fronts and pressure systems and can blow at any hour, so the forecast decides the day rather than the clock. Summer highs sitting to the east are what deliver the steadier easterlies.

fills in: No thermal cycle to time. Wind arrives with fronts and pressure systems and can blow at any hour, so the forecast decides the day rather than the clock. Summer highs sitting to the east are what deliver the steadier easterlies.
Typical strength
Light and gusty. Most rideable days sit at 2-3 Bft, roughly 7-12 kt; a good one reaches 4 Bft, about 11-16 kt, and the strong frontal days gust to 6 Bft. Around 30 kiteable days a year is the honest count, and only for someone who can go at short notice. Nothing measures wind at Allmannsdorf itself; the closest on-lake record, a station at Ramsberg on the south shore that ran from September 2017 to January 2020, averaged 5 kt with gusts of 6 kt and stopped reporting.
Thermal or synoptic
synoptic/front-driven inland wind
The quiver, in words
No local size guidance is published. Indicative for a 75-85 kg rider on this lake: 15-17 m or a light-wind foil kite on the usual 7-12 kt, 12-13 m on a 4 Bft day, 9-10 m on the rare strong front. Gusts run far above the mean, so pick the size that gets you moving in the lull.
Direction to shore
W is sideshore from the right at the Allmannsdorf dam-side launch; E is also described as usable by Spotnetz/Pleinfeld; NW is wind-shadowed and gusty.
Dominant direction
W, WSW and SW are the directions usually given for Allmannsdorf, while east wind is also rated especially good on this north shore. The two claims conflict and neither is settled.

The model is wrong here
The model reads 8% of days at its best month, which does not sit with the wind strength this record states. The figures are kept and drawn as hatching so no wind colour can be read off them.

modelled
A weather model covers this place, but its figures do not sit with the wind strength this record states, so no season is drawn from them. They are in the table above, and no riding season is on record either.
Modelled from the operational forecast archive at 1.5–7 km (2023-2024), daylight hours only, not a ground station: it resolves thermal, lake and valley winds far better than coarse reanalysis but still tends to understate a strong local thermal. A windy day has at least three consecutive daylight hours at 12 knots or more. The typical daily max and the direction are columns of the table above, month by month.

Rules & access
Access rules drift faster than anything else we hold — check locally, and propose an edit if this has changed.
Rider tips
- Skip west wind unless you can hold height: the dam is about 100 m downwind in the lee.
- Ask the school or whoever is rigging whether Allmannsdorf or Ramsberg suits the day's exact wind angle.
- Keep off the passenger steamer's line across the lake.
- Budget for paid parking and a 200-300 m carry from the car to the water.
- On sunny east-wind days, launch clear of the bathers instead of through them.

FAQ
Is Allmannsdorf suitable for beginners?
No, the shore drops steeply and the standing-depth area is very small, so KITE Magazin recommends beginners take lessons rather than ride independently.
What is the wind like?
West and southwest are the main working directions and arrive cleanly, while northwest is very gusty because of wind shadow from the shoreline.
What are the main hazards?
In west wind the dam sits only about 100 m downwind, so riders who cannot hold their ground can be pushed onto it; passenger ferry traffic also crosses the lake.
Are there kite schools nearby?
Yes, Surf- und Kiteschule Brombachsee operates directly at Allmannsdorf, offering surf, SUP and kite courses.
