Details: the drivers behind the forecast Allmannsdorf
This page shows the main drivers of the wind system on the lake as a forecast for the next 4 days. How the forecast works
The dashed line is a limit from our measurements: once the west wind aloft reaches the line, there is usually wind on the lake as well.

Wind systems at this spot
At Allmannsdorf, a southwest wind works best. The lake runs from west-southwest to east-northeast, and at the eastern end in Allmannsdorf, the southwest wind blows across the entire length of the lake.
Due to the west-east orientation of Lake Brombach, the wind can flow across the lake largely unimpeded. The elevation relative to the natural topography further enhances the wind conditions. Particularly suitable wind directions are southwest to west-southwest, as well as east to southeast. The best wind conditions often occur before and after the passage of low-pressure systems. However, stable easterly wind conditions are also suitable. Winds from the northwest, north, or northeast blow over land and forest and barely reach Allmannsdorf. If northwest winds are forecast, Brombachsee is not the best spot. Thermal winds do not generate wind here.
The above description always refers to the respective measuring station and the model calculated from the measurement data and should not be understood as a general, standard spot guide for the entire lake.
The drivers
Upper wind west/east
Calculated and shown is the wind at about 1.5 km altitude (850 hPa) above the lake: upwards the share from the west, downwards the share from the east, plus the direction (right axis).
At Lake Brombach the wind comes almost only with a westerly weather pattern. The lake runs from west-southwest to east-northeast, and at Allmannsdorf at the eastern end the southwest wind blows in over the whole length of the lake. Only from about 25 knots of west wind aloft was there any wind on the lake at all in our measurements, from about 40 knots in every fifth hour between 8 am and 7 pm.
Wind from the northwest, north or east comes over land and forest and hardly reaches Allmannsdorf. If northwest or east wind is forecast, Lake Brombach is not the best spot.
