                 SEPTEMBER WEATHER IN SAN DIEGO

SEPTEMBER IS USUALLY THE TIME WHEN WE START TO SEE THE APPEARANCE OF
HOT...DRY EASTERLY WINDS KNOWN AS SANTA ANAS. IT WAS DURING ONE
OF THESE OCCURRENCES THAT THE ALL TIME HIGH OF 111 DEGREES WAS
RECORDED ON SEPTEMBER 26...1963. HOWEVER...MONTHLY AVERAGES HAVE
BEEN CHANGED LITTLE BY THE OCCASIONAL HOT DAYS. THE NORMAL MAXIMUM
IS ONLY 75.9 DEGREES...THE NORMAL LOW 65.2 DEGREES AND THE NORMAL
MONTHLY AVERAGE 70.6 DEGREES. THE LOWEST RECORDED TEMPERATURE WAS 50
DEGREES ON THE 18,19 1882 AND 26 1907.

OUR DRY SEASON CONTINUES THROUGH SEPTEMBER AND IN MORE THAN HALF
OF THE YEARS NO MEASURABLE AMOUNTS OF RAIN WERE RECORDED DURING
THE MONTH.  THE NORMAL RAINFALL IS 0.15 INCH WITH THE GREATEST
MONTHLY TOTAL 2.58 INCHES IN 1939. THE LAST YEAR DOWNTOWN HAD
MEASURABLE RAINFALL WAS IN 2011 WHEN 0.07 FELL ON THE 5TH AND
0.06 FELL ON THE 6TH.

AS A GENERAL RULE...THE NIGHT AND MORNING OVERCAST SKIES OF SUMMER
BECOME LESS PERSISTENT...BUT THE RELATIVE HUMIDITY REMAINS HIGH. AT
THE TIME OF THE EAST WINDS...THOUGH...SEVERAL DAYS OF DRY WEATHER
AND EXTREMELY LOW HUMIDITY CAN PREVAIL. CLEAR DAYS AVERAGE
15...PARTLY CLOUDY 9 AND CLOUDY 6 WITH AN AVERAGE OF 2 DAYS OF HEAVY
FOG.
