How to extract the specific rows from the table?

There are total of 30 years precipitation data (Januaray to December).

There are only one column with January to December.

How can I extract or select June to August of 30 years?

If you need to, adjust there is ismember() the month column against the appropriate representation of the months you are interested in.

ismember(t.Month,{'June','July'})

for example.
