TOTAL RAINFALL...............  0.54 DEPARTURE FROM NORMAL..... +0.36
TOTAL SINCE JANUARY 1ST...... 27.31 DEPARTURE FROM NORMAL.....  3.85
TOTAL SINCE OCT 1ST.......... 48.03 DEPARTURE FROM NORMAL.....  8.60

HIGHEST SLP......... 30.24 ON 22 LOWEST SLP........29.78 ON 30

...REMARKS...TEMPERATURES THIS MONTH WERE VERY CLOSE TO NORMAL.
THIS WAS DUE IN PART TO PERSISTENT HIGH PRESSURE OVER THE INLAND
AREAS WHICH BROUGHT STRONG NORTHERLIES TO THE COASTAL WATERS. THIS
CAUSES UPWELLING WHICH BRINGS COOL WATER TO THE OCEAN SURFACE.

HIGH TEMPERATURES WERE WITHIN A DEGREE OF NORMAL AND LOW
TEMPERATURES WERE ONE DEGREE ABOVE NORMAL. THIS IS IN FAIRLY STARK
CONTRAST TO A YEAR AGO. IN JULY 2015 HIGH TEMPERATURES WERE 3.6
DEGREES ABOVE NORMAL AND LOW TEMPERATURES WERE 3.1 DEGREES ABOVE
NORMAL. THE RANGE OF TEMPERATURES THIS YEAR WAS ALSO VERY SMALL
WHICH IS TYPICAL IN JULY. THE WARMEST DAY WAS 67 DEGREES AND THE
COOLEST NIGHT WAS 49 DEGREES.

RAINFALL WAS ABOVE NORMAL FOR THE MONTH WITH SLIGHTLY OVER A HALF
INCH OF RAIN. MOST OF THIS RAIN FELL ON THE 8TH THROUGH THE 9TH WITH
A RECORD OF 0.30 INCHES MEASURED ON THE 8TH. THIS BROKE THE OLD
RECORD OF 0.22 INCHES SET IN 1964.
