July is the last month that “Normal” readings were based on averages calculated over the period of 1971-2000.  August averages will now be based upon new climatic “Normals” based upon the period 1981-2010. We have been hearing and reading about how our climate in Tucson is now warmer and drier. These new “Normals” reflect that trend.

For January through July 2011 the new averages compare as follows:
