Maybe the keyword `method='nearest'` will be useful to you?

I am not wanting a range of values that is why I don't want to use slice - I just want the value at the given time, latitude and longitude. 

If I use .isel() I receive an 'Assertion Error' on this line:
MaxTempatpoint=MaxTempattime.isel(latitude=-39.14952469, longitude=140.84791565)

and if I use .sel() I receive a 'Key Error' -  KeyError: -39.14952469  on this line:
MaxTempatpoint=MaxTempattime.sel(latitude=-39.14952469, longitude=140.84791565)

I haven't pasted entire error message because I am assuming the issue I am having is simple?? 

Should I some how convert the latitude and longitude to a different data type and then access? Or is there some way of accessing an index for the latitude and longitude?
Any feedback will be greatly appreciated.

Note that `.isel()` is for integer indexing while `.sel()` is for indexing by value (probably what you want).

if you want a range of values you should give a slice as argument, as indicated in the [documentation](http://xarray.pydata.org/en/stable/indexing.html#indexing-with-labeled-dimensions): e.g. `.sel(longitude=slice(34, 67))`

(PS: when you report a problem it would be useful to also post the error message, which is more informative than ""#this is where the problem occurs"")
