Coldest July ever!
Posted by JAC on 8/3/2009, 2:53 pm



July 2009 goes into the record books as the coolest July ever in Grand Rapids, MI with an average temperature (an average of all the high and low temperatures for the month) of 67.1F.

Its also the first July when the temperature in Grand Rapids failed to reach 85F.  

July has been trending cooler, not warmer in recent decades.  

Four of the seven coolest Julys in G.R. have occurred since 1992.  

All ten of the warmest Julys occurred prior to 1956.  

Records go back to 1892.  Theres no global warming evident in this long-term (118 years) July climate data for Grand Rapids and most of the Great Lakes and Midwest.  

Des Moines IA hasnt set a record high temperature in July since 1955.  

It was also the coolest July ever in Kalamazoo (67.5F) Gaylord (61.3F) Houghton Lake (62.0F), Rockford, IL (67.0F - a full 2.0F); cooler than the previous record coolest set in 1915), South Bend (68.3F- records began in 1893), Fort Wayne (68.9F), International  Falls, MN (58.8F not a single day warmer than normal and they didnt hit 80F all month), Madison, Wisconsin (65.7F), Burlington IA (70.2F), Cedar Rapids (66.2F), Dubuque 65.5F) and Marion IA (68.6F).  

The highest temperature in Madison WI all month was only 82F - again the coolest monthly maximum ever.  

Chicago had the 2nd coolest July since 1942, when the city's official thermometer was moved from the lakeshore to the airport in the western suburbs.  

Rochester, NY had their coolest July in 125 years (66.2F) and the coolest June-July period ever.

Lansing MI ended up in 5th place for coolest July at 66.6F with an all-time record coolest maximum temperature for the month at 84F.  

Muskegon's average July temperature of 65.9F made it the coolest July since 1924.

Here's an oddity: Pellston MI had as many nights in the mid 30s in July as they had days in the low 80s (2).  Boston and New York had the coolest June/July since 1903.
