The structure is quite static, you could also use the __DATA__ part of your script. A possible approach could be: 
#!/usr/bin/perl

# Load data inside %times hash
my %times;
while (<DATA>) {
   next unless /\S/; # just in case...
   my ($month, $weeknum, $day, $val) = split /;/;
   $times{$month}{"wk$weeknum"}{$day} = $val;
}

# ... all your program here ...


__DATA__
May;1;Mon;24.50
May;1;Tues;23.40
May;1;Wed;22.40
May;1;Thu;25.01
May;1;Fri;24.10
... and so on...

However, you should decide which is the best data structure suitable for what you intend to do with your data, then think about how storing it somewhere. You can also look for Storable or XML::Simple for ways to do the latter.

Flavio (perl -e 'print(scalar(reverse("\nti.xittelop\@oivalf")))')

Don't fool yourself.
