How to plot monthly averages on a map?

I have a netcdf file (attached zip file-'yl'). There is a temperature variable 'to' available from Jan-1993 to Jan-2017. Using ncread, the time values are 'hours since 1950' and each value corresponds to one month i.e. Jan 1993, Feb 1993 ..... Jan 2017.

I wanted to plot average summer (May-Jun) temperatures on a map.

I attached a picture for reference.

Would be grateful to receive some help in this.

Read the variable and use mean. YOu can specify the dimensions along wheich you want mean and then plot the data.
