If you insist on using XPath, here's a version. But in this case, I'd say using something like XML::Simple is simpler. 
use strict;
use XML::XPath;

my $month = 1;
my $min = 30;
my $match = findmax($month,$min);
foreach my $t(@$match){
    print "$t->[0],$t->[1]\n";
}


sub findmax{
    my $month = shift;
    my $min = shift;
    $month = "-$month-";
    my @result = ();
    
    my $xp = XML::XPath->new(filename => 'test.xml');
    my $nodes = $xp->findnodes("//DailyWeatherRecord[contains(date,'$m
+onth') and temperature/maxdrybulb[\@number>$min]");
    foreach my $node($nodes->get_nodelist){
        push @result,[$xp->findvalue("./date",$node),$xp->findvalue(".
+//maxdrybulb/\@number",$node)];
    }
    return \@result;
}
