Detroit's January 2012 average
temperature was 30.7°F or 5.1°F above the current 30-year Normal.
This is in contrast with
January 2011 where the temperature was -2.7°F below the normal at 21.8°F.
| The new 1981-2010 climate
normals are currently being released by NCDC. This report does NOT include
the new daily normals but beginning with the CDD (cooling) season reports
the new daily normals will be used. Attached is a comparison of the old
1971-2000 to the new 1981-2010 Detroit Normals. Note that due to warmer
temperatures during the 1990's the number of normal HDD's will go down
while the normal CDD's will go up.
