With only 58 points, you will not get a lot of spatial detail, no matter what interpolation method you use. For example, using 58 points to create a surface with e.g. 1 million points is a waste of time: there is simply not enough spatial detail in the input. You can check, as you have done, by changing the resolution of the current region for the output and comparing the results. The only solution for more spatial detail is to get more input points.
Markus, Thanks for the insight. Yes, there are too few data points for the size of the area. So, I'll not use this map, but present a table of annual mean values instead.
