OK, first you need to load the dataset, and from data source properties window 
do the spatial and time subset. 
There will be a lot of clicks to select these time steps from June to August.

Second, Formula > Define a grid diagnostic, and select your display type, when 
a window popup, enter

makeVector( averageOverTime(a), averageOverTime(b))

then a new popup will ask you to select a, b which should be  U, V in your 
dataset. That should create a display of what you want.
