MOST OF THE LAST HALF OF THE MONTH SAW BELOW NORMAL TEMPERATURES WITH BRIEF PERIODS OF WARMER WEATHER. DAILY HIGH TEMPERATURES WERE SLIGHTLY BELOW NORMAL IN JULY BUT THIS WAS OFFSET BY LOW TEMPERATURES WHICH WERE THE NINTH WARMEST EVER RECORDED IN THE MONTH OF JULY. OVERALL THE AVERAGE TEMPERATURE FOR THE MONTH WAS 69.8 DEGREES WHICH WAS 0.7 DEGREES ABOVE NORMAL. ALTHOUGH JULY WAS ABOVE NORMAL... IT WAS THE COOLEST JULY SINCE 2009 (AVERAGE TEMPERATURE 66.2). THE WARMEST JULY ON RECORD WAS 2011 WITH AN AVERAGE TEMPERATURE OF 72.7 DEGREES. THE COOLEST JULY WAS 1962 WITH AN AVERAGE OF ONLY 64.0 DEGREES.

THIS WAS ALSO THE WARMEST TEMPERATURE OF THE YEAR... AND THE ONLY TIME THIS YEAR THAT THE TEMPERATURE HAS RISEN ABOVE 85 DEGREES. NEVER BEFORE HAS PORTLAND WAITED THIS LONG IN THE YEAR TO RISE ABOVE 85 DEGREES. THE PREVIOUS RECORD WAS IN 1996 WHEN THE TEMPERATURE FIRST ROSE ABOVE 85 ON JULY 18. IF THE TEMPERATURE DOES NOT RISE ABOVE 87 DEGREES THE REST OF THE YEAR... THEN THIS WILL TIE AS THE SECOND COOLEST YEARLY HIGH TEMPERATURE AT PORTLAND. THE RECORD WAS 1996 WHEN THE WARMEST TEMPERATURE OF THE YEAR WAS 86 DEGREES. PORTLAND HAS NOT REACHED 90 DEGREES THIS YEAR. IF THIS TREND CONTINUES IT WILL BE THE FIRST TIME SINCE 2008 THAT PORTLAND DID NOT REACH 90 DEGREES. NORMALLY PORTLAND SEES 4.6 DAYS PER YEAR AT 90 OR ABOVE. ONLY 6 TIMES HAS PORTLAND FAILED TO REACH 90 DEGREES IN A YEAR. THIS IS ROUGHLY 8 PERCENT OF ALL YEARS IN THE PREVIOUS 73 YEARS OF TEMPERATURE RECORDS AT PORTLAND.
