Something like this,
you can assign month to variable and loop for getline.
Code:
awk -v mon=3 '
BEGIN{print "depth\ttemp\tsalinity"}
/<Depth/ {split($2,a,"\"");depth=a[2]}
/<Temperature/ {for (i=1;i<=mon;i++) {getline};temp=$1}
/<Salinity/ {for (i=1;i<=mon;i++) {getline}salinity=$1;printf "%d\t%d\t%d\n",depth,temp,salinity}
' lat_060_lon_003.xml
