...Denver's Preliminary 2007 Climatological Annual Statistics...
There was nothing spectacular in Denver's 2007 annual climatological statistics. None
of the annual statistics made it into the top ten annual categories...warmest ...
coldest... wettest...driest...snowiest and/or least snowiest. Temperatures extremes in
2007 ranged from minus 18 degrees on February 2nd up to 100 degrees recorded on June
24th...July 2nd and July 17th. The minus 18 temperature was a new February 2nd daily
record. The July 2nd 100 degree reading tied a daily record but the July 17th 100
degree reading was not high enough to tie or break the record for that date. The
average temperature for the year through December 30th was slightly above normal.
Precipitation for the year was 14.00 inches which was 1.81 inches below the yearly
normal (15.81 inches). Snowfall for the calendar year...which is January through
December...was 55.4 inches which is 6.3 inches below the 61.7 inch normal. Seasonal
snowfall is measured from July 1st through June 30th. So far...July through
December...26.4 inches has been tallied which is only 0.8 inch above the seasonal
average for the 1st half of the 2007-2008 season. There were 18 different types of
records tied or set during the year. In the snowfall category...there was 7.8 inches
recorded on Christmas Day which was a new record snowfall for December 25th. The
previous Christmas Day record was 6.2 inches...recorded in 1894.
