Preliminary June 2009 Climate Information for NWS Marquette

June 2009 was another month that contained up and down temperatures.  The first half of the month was well below normal, with an average temperature through June 15th of 50.4 degrees.  This was nearly 8 degrees below normal for the first 15 days and the 2nd coldest June 1-15th on record (the coldest was 50.0 degrees in 1969).  In addition, June 8th had the 9th coldest June high temperature recorded (46 degrees).  

Temperatures rebounded during the second half of the month, with 5 days during the second half topping 80 degrees.  The warm days and nights produced an average temperature from June 16-30th of 65.0 degrees (2.8 degrees above normal).  This caused June 16-30, 2009 to be the 12th warmest second half of June on record, with the warmest occurring in 1995 (73.0 degrees). But the second half warm up wasn't enough to bring the monthly temperatures back to normal.  The up and down temperatures during the month can be seen in the chart below.
