Hi, @mathause. Thanks for reporting.

I agree that this behavior is a little surprising, but this is something expected. The difference is not skipna=True (both use this), but actually in min_periods. If you specify min_periods=1, then the results become identical. python In [7]: ds.rolling(dim=3, center=True, min_periods=1).mean() Out[7]: <xarray.DataArray (dim: 4)> array([0.5, 1. , 2. , 2.5]) Dimensions without coordinates: dim

I am not sure how we can make both the behaviors the same with keeping the generality of construct method.
