I tracked this down to the difference between reading the file remotely, or downloading first and accessing a local copy on v0.20.2 (the latter is what I used to produce my figures). Can you reproduce?
```
remote = xr.open_dataset(
""http://kage.ldeo.columbia.edu:81/SOURCES/.LOCAL/.sst.mon.mean.nc/.sst/dods""
).sst.sel(lat=20, lon=280, method=""nearest"")
local = xr.open_dataset(""~/Downloads/data.cdf"").sst.sel(lat=20, lon=280, method=""nearest"")
```
```
(remote.groupby(""time.month"") - remote.groupby(""time.month"").mean()).plot()
```
```
(local.groupby(""time.month"") - local.groupby(""time.month"").mean()).plot()
```

I get a plot that looks quite similar
