awk regex calculation for certain range only

awk regex calculation for certain range only

awk regex calculation for certain range only

Once again I need a hint for awk. My aim is to do two calculations on a specific part of a field.
But for the beginning I'll start with one calculation.
If this regex prints all the lines to stdout

CODE --> awk

awk '$3 ~ /^June$/' datafile.txt 
my task is to fetch the maximum and average for that specific part.
My first attempt gives me all the lines for that month, but I need only the result for that month, beside that it prints to stdout a last line with the name of the matched regex.

CODE --> awk

awk '$3 ~ /^June$/; {if ($2>max) max=$2}  END { print max};' datafile.txt 
How to make that calculation for only the range of the regex $3 ~ /^June$/; and print just the result without all the other lines?

Can anybody help? Thanks in advance.
