September 2011 started out very hot with the first 8 days recording high
temperatures between 100 - 106 degrees F ( 37.8 - 41.1 C). The rainfall at the
airport set a record of 5.6 inches (142.24 mm) for the month. Much of that rain,
2.84 in (72.14 mm) fell in one record breaking monsoon storm. Not all of Tucson
experienced as much rain. My location only received a total of 1.23 in (31.24 mm)
for the whole month.
