The way this should work is that the selection of a single point should happen before the data is concatenated. It is up to dask to properly "fuse" these two operations. It seems like that is failing for some reason.

As a temporary workaround, you could preprocess the data to only select the specific point before concatenating. python def select_point(ds): return ds.sel(latitude=10, longitude=10) ds = xr.open_mfdataset('*.nc', preprocesses=select_point)

But you shouldn't have to do this to get good performance here.
