FOR THE THIRD STRAIGHT MONTH PORTLAND EXPERIENCED TEMPERATURES
SLIGHTLY ABOVE NORMAL. FOR MOST OF THE FIRST TEN DAYS OF THE MONTH
PORTLAND SAW WARM WEATHER. HURRICANE ARTHUR PASSING BY OFFSHORE
BROUGHT HEAVY RAIN AROUND THE FOURTH OF JULY. 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.

THE TABLE BELOW LISTS THE WARMEST AVERAGE LOW TEMPERATURES FOR THE
MONTH OF JULY. 7 OF THE TOP TEN WARMEST AVERAGE LOWS HAVE OCCURRED
SINCE 1999.

THE WARMEST TEMPERATURE OF THE MONTH WAS 87 DEGREES ON THE 23RD.
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. BELOW IS A LIST OF THE
COOLEST YEARLY MAXIMUM TEMPERATURES AT PORTLAND.
